This is due to the architecture of the system where Dirmngr is the sole process responsible for network related tasks. Network access is required for: - CRL fetching and caching for S/MIME - OCSP checking - S/MIME (X.509) certificate search via LDAP - OpenPGP keyserver access (HTTP, LDAP, etc.) - Checking for software updates (if enabled) In the following we describe how S/MIME and OpenPGP certificate search is implemented. If you want to skip this background information feel free to continue with the next section where LDAP installation and configuration is described. In any case we need to explain a few terms used with LDAP: - DIT :: /Directory Information Tree/ also known as /naming context/. This is is often referred to as the /LDAP directory/. It is where the data for a single organization described by a DNS name is stored (e.g. "example.org"). - DN :: /Distinguished Name/ is the key for an entry in the DIT. It is a similar concept as used in the DNS system. - RDN :: /Relative Distinguished Name/ is a component or part of a DN. For example the DN "cn=admin,dc=example,dc=com" consist of the 3 RDNs "cn=admin", "dc=example", and "dc=com". Each RDN has a name (e.g. "cn" for /common name/ or "dc" for /domain component/) and a values (e.g. "admin"). - LDIF :: /LDAP Data Interchange Format/ is a description for the human readable data exchange format used with LDAP. ** OpenPGP To serve OpenPGP certificates via LDAP a dedicated schema needs to be installed. The schema supported by GnuPG was originally defined by PGP Inc. in the end of the 1990ies. This is today still the schema installed on LDAP servers for access by PGP or GnuPG. However, this schema has a couple of deficits which need to be fixed. For that reason we have defined additional attributes. These new attributes eventually allow to lookup certificates by their fingerprints and not just by the shorter and thus non-unique Key-ID. The new schema also supports storing of information on the subkeys and the UTF-8 encoded mail addresses. Current versions of GnuPG do not yet make use of these new attributes but for new LDAP installations it is highly recommended to use the new schema so that a future version of the software can make use if these attributes. Note that the OpenPGP certificates are stored in the DIT under a separate organizational unit using the long Key-ID to distinguish them. An example for such an DN is: : pgpCertID=63113AE866587D0A,ou=GnuPG Keys,dc=example,dc=com or for Active Directory : cn=C312[...]0A,cn=GnuPG Keys,dc=example,dc=com This design means that entries stored under "GnuPG Keys" are not connected to the users commonly found on an LDAP server. This allows to store arbitrary OpenPGP certificates in the directory and is commonly used to make the certificates of external communication partners easily available. ** S/MIME Standard X.509 LDAP semantics apply for S/MIME certificate search. The current version of Dirmngr (2.2.23) supports 3 pattern formats which are translated from GnuPG's User-ID syntax, as given to the gpg and gpgsm commands, to the LDAP syntax: - Mail :: Indicated by a leading left angle and translated to the query: : "" -> "mail=ADDRSPEC" - Subject DN :: Indicated by a leading slash. The DN is formatted according to RFC-2253 rules and thus directly usable for an LDAP query. - Substring search :: If no other syntax matches or the pattern is prefixed with an asterisk the User-ID is translated to: : "USERID" -> "(|(sn=*USERID*)(|(cn=*USERID*)(mail=*USERID*)))" or in other word a substring search on the serial-number, the common-name, and the mail attribute is done. The result is expected to be in one of the attributes "userCertificate", "cACertificate", or "x509caCert". In cases where we are looking for the issuer certificate only "cACertificate" is used. "ObjectClass=*" is always used a filter. Note: The attribute "mail" with the OID 0.9.2342.19200300.100.1.3 was originally defined with this OID under the name "rfc822Mailbox" using a different although similar syntax. Take care: This is not an UTF-8 encoded mail address and in theory GnuPG should use IDN mapping here. However, it is questionable whether any real world installation would be able to handle such a mapping. * How to install OpenLDAP To install a standard LDAP server to provide S/MIME certificate lookup follow the instructions of your OS vendor. For example on Debian based systems this is: : apt-get install slapd ldap-utils libsasl2-modules Follow the prompts during installation, set an initial admin password, and, most important, the domain you want to serve. Note that we use "example.com" in following. If you ever need to change the configuration on a Debian based system you can do so by running : dpkg-reconfigure slapd Serving LDAP requests for S/MIME (X.509) certificates will then work out of the box. Use your standard tools to maintain these entries. Some hints on how to manually add certificates can be found below in the section "Useful LDAP Commands". Please read on if you want to serve also OpenPGP certificates. ** Installation of the OpenPGP Schema Assuming a standard OpenLDAP installation, it is easy to add a new schema to store OpenPGP certificate. We describe this now step by step. First you need to download the two LDIF files - https://gnupg.org/misc/gnupg-ldap-schema.ldif - https://gnupg.org/misc/gnupg-ldap-init.ldif. As administrator (root) on your LDAP server use the command : ldapadd -v -Y EXTERNAL -H ldapi:/// -f ./gnupg-ldap-schema.ldif to install the schema. The options given to the ldapadd tool are: - -v :: Given some diagnostic output (be verbose). To be even more verbose you may use =-vv= or =-vvv=. The diagnostics are written to stdout. - -Y :: Specify the authentication mechanism. Here we use =EXTERN= which is in this case local socket based authentication (ldapi). - -H :: The URL to access the LDAP server. Only scheme, host, and port are allowed. In our case we use =ldapi:///= to request a connection on the standard OpenLDAP socket (usually this is =/var/run/slapd/ldapi=). - -f :: Specify a file with data to add to the directory. The file used here is the specification of the keyserver schema. If this option is not used ldapadd expects this data on stdin. The new schema should now be installed. Check this by using this command: : ldapsearch -Q -Y EXTERNAL -L -H ldapi:/// \ : -b 'cn=schema,cn=config' cn | grep cn: (on Unix the backslash indicates that the line is continued with the next line) The options not used by ldapsearch which have not yet been explained above are: - -Q :: Be quiet about authentication and never prompt. - -b :: Specify the search base. In this case we want the internal OpenLDAP schema which stores the server's own configuration. The final argument =cn= restricts the output to the DN and the CN attribute; the grep then shows only the latter. With a freshly installed OpenLDAP system you should get an output like: #+begin_example cn: schema cn: {0}core cn: {1}cosine cn: {2}nis cn: {3}inetorgperson cn: {4}gnupg-keyserver #+end_example This tells you that the keyserver schema has been installed under (in this case) the index "{4}". The next step is to connect the new schema with your DIT. This means that entries to actually store the certificates and meta data are created. This way GnuPG will be able to find the data. For this you need to edit the downloaded file =gnupg-ldap-init.ldif= and replace all the RDNs with name "dc" with your own. For example, in our own LDAP we would change : dn: cn=PGPServerInfo,dc=example,dc=com to : dn: cn=PGPServerInfo,dc=gnupg,dc=com and do that also for the other 3 appearances of the "dc" RDNs. In case you use a 3-level domain, add another "dc" in the same way you did when setting up OpenLDAP. With that modified file run : ldapadd -v -x -H ldapi:/// -D 'cn=admin,dc=example,dc=com' \ : -W -f ./gnupg-ldap-init.ldif Remember to change the "dc" RDNs also here to what you actually use. We use simple authentication by means of these options: - -x :: Use simple authentication - -D :: The Bind-DN used to bind to the LDAP directory - -W :: Ask for the admin's passphrase. You may also use a lowercase =-w= followed by the passphrase but that would reveal the passphrase in the shell's history etc. All users with access right to the LDAP server may now retrieve OpenPGP certificates. But wait, we also need a user allowed to insert or update OpenPGP certificates. Choose a useful name for that user and create a file =newuser.ldif=. In our example domain we name that user "LordPrivySeal" and thus the file is: #+begin_src dn: uid=LordPrivySeal,ou=GnuPG Users,dc=example,dc=com objectClass: inetOrgPerson objectClass: uidObject sn: Lord Keeper of the Privy Seal cn: Lord Privy Seal userPassword: {SSHA}u6oxl9ulaS57RPyjApyPcE7mNECNK1Tg #+end_src The =userPassword= has been created by running : /usr/sbin/slappasswd entering the password, and paste the output into the file (the password used in the above example is "abc"). Now run : ldapadd -v -x -H ldapi:/// -D 'cn=admin,dc=example,dc=com' \ : -W -f ./newuser.ldif On the password prompt enter the admin's password (not the one of the new user). Note that the user is created below the "GnuPG Users" organizational unit and not in the standard name space. Thus this is a dedicated user for OpenPGP certificates. See below how you can list the entire DIT. With a fresh install you should see these DNs: #+begin_example dn: dc=example,dc=com dn: cn=admin,dc=example,dc=com dn: cn=PGPServerInfo,dc=example,dc=com dn: ou=GnuPG Keys,dc=example,dc=com dn: ou=GnuPG Users,dc=example,dc=com dn: uid=LordPrivySeal,ou=GnuPG Users,dc=example,dc=com #+end_example Finally we need to give all users read access to the server's database and allow an authenticated user to modify the database. To do this you need to figure out the used database; run the command : ldapsearch -Q -Y EXTERNAL -H ldapi:/// -b 'cn=config' dn | grep olcDatabase= which should give you a list like this: #+begin_example dn: olcDatabase={-1}frontend,cn=config dn: olcDatabase={0}config,cn=config dn: olcDatabase={1}mdb,cn=config #+end_example The first two databases are for internal purposes, the last one is our database. Now create a file =grantaccess.ldif= with this content: #+begin_example dn: olcDatabase={1}mdb,cn=config changetype: modify replace: olcAccess olcAccess: {0} to dn.subtree="dc=example,dc=com" by dn.regex="^uid=LordPrivySeal,ou=GnuPG Users,dc=example,dc=com" write by * read #+end_example As usual replace all "dc=example,dc=com" accordingly. Take care not to insert a blank line anywhere. The first line needs to give the DN of the database as determined above. Excute the rules from that file using the command: : ldapmodify -Q -Y EXTERNAL -H ldapi:/// -f grantaccess.ldif Now all users have read access and the user LordPrivySeal has write access. In case you want to give several users permissions to update the keys replace the regex line in =grantaccess.ldif= with : by dn.regex="^uid=([^,]+),ou=GnuPG Users,dc=example,dc=com" write (take care to insert two spaces at the begin of the line.) Then create those users below the RDN "ou=GnuPG Users". That's all you need to do at the server. ** Configuration for GnuPG The easiest way to enable LDAP for S/MIME is to put #+begin_src keyserver ldap.example.com::::dc=example,dc=com: #+end_src into =gpgsm.conf=. If you prefer to use a dedicated configuration file you can do this with dirmngr by adding a line : ldap.example.com::::dc=example,dc=com: to =dirmngr_ldapservers.conf=. Assuming you want to use the machine running the LDAP server also to maintain OpenPGP certificates, put the following line into the =dirmngr.conf= configuration of a dedicated user for this task: #+begin_src keyserver ldapi:///????bindname=uid=LordPrivySeal %2Cou=GnuPG%20Users%2Cdc=example%2Cdc=com,password=abc #+end_src (Enter this all on one line; "%2C" directly at the end of "Seal") That is a pretty long line with weird escaping rules. Just enter it verbatim but replace the "dc" RDNs accordingly. Remember that =ldapi= uses local socket connection instead of TCP to connect to the server. The password given in that file is the password of the OpenPGP maintainer (LordPrivySeal). Use appropriate permissions for that file to make it not too easy to access that password. See the GnuPG manual for other ways to configure an LDAP keyserver. With that configuration in place you may add arbitrary OpenPGP keys to your LDAP. For example user "joe@example.org" sends you a key and asks to insert that key. If you feel comfortable with that you should first check the key, import it into your local keyring, and then send it off to your LDAP server: : gpg --show-key < file-with-joes-key.asc Looks good? Note the fingerprint of the key and run : gpg --import < file-with-joes-key.asc : gpg --send-keys FINGERPRINT That's all. If you want to work from a different machine or use the Kleopatra GUI you need to make sure that ldaps has been correctly configured (for example on the machine =ldap.example.org=) and you need to use this keyserver line: #+begin_src keyserver ldaps://ldap.example.com/????bindname=uid=LordPrivySeal %2Cou=GnuPG%20Users%2Cdc=example%2Cdc=com,password=abc #+end_src (Enter this all on one line; "%2C" directly at the end of "Seal") The easier case is the configuration line for anonymous users which is a mere #+begin_src keyserver ldaps://ldap.example.com #+end_src This assumes that you have a valid TLS server certificate for that domain and ldaps is enabled on the server. * Useful OpenLDAP Commands ** List the entire DIT To list the entire DIT for the domain "example.com" use this command: : ldapsearch -Q -Y EXTERNAL -LLL -H ldapi:/// -b dc=example,dc=com dn This lists just the DNs. If you need the entire content of the DIT leave out the "dn" argument. The option "-LLL" selects useful formatting options for the output. ** Insert X.509 Certficate If you don't have a handy tool to insert a certificate via LDAP you can do it manually. First put the certificate in binary (DER) format into a file. For example using gpgsm: : gpgsm --export berta.boss@example.com >berta.crt Then create a file =addcert.ldif=: #+begin_example dn: CN=Berta Boss,dc=example,dc=com objectclass: inetOrgPerson cn: Berta Boss sn: Boss gn: Berta uid: berta mail: berta.boss@example.com usercertificate;binary:< file:///home/admin/berta.crt #+end_example (Note that an absolute file name is required.) Finally run : ldapadd -x -H ldapi:/// -D 'cn=admin,dc=example,dc=com' -W -f adduser.ldif ** Setup TLS certificates Create a file =tlscerts.ldif=: #+begin_example dn: cn=config changetype: modify replace: olcTLSCACertificateFile olcTLSCACertificateFile: /etc/ssl/certs/Example.com-Root-CA.pem - replace: olcTLSCertificateFile olcTLSCertificateFile: /etc/ssl/mycerts/ldap.example.com.pem - replace: olcTLSCertificateKeyFile olcTLSCertificateKeyFile: /etc/ssl/private/ldap.example.com.key #+end_example Make sure that the user under which slapd is running has access to all these files. The key file should only be readable by that user or group. Then run : ldapmodify -v -H ldapi:// -Y EXTERNAL -f tlscerts.ldif In case you run into a the error message “Other (e.g., implementation specific) error (80)” check the file permissions, restart slapd so that it takes up a group modification you did, check that the order of the item is exactly as given above. For a quick test whether this works use this command: : LDAPTLS_CACERT=/etc/ssl/certs/Example.com-Root-CA.pem \ : ldapwhoami -v -H ldap://ldap.example.com -ZZ -x (-ZZ enforces the use of STARTTLS) # Note: To enable the legacy ldap-over-tls put "ldaps:///" into the # list of URLs give to the slapd option -h. For example: # # slapd -h "ldap:/// ldaps:/// ldapi:///" ... # # To test this use # # LDAPTLS_CACERT=/etc/ssl/certs/Example.com-Root-CA.pem \ # ldapwhoami -v -H ldaps://ldap.example.com -x # If you use a custom Root-CA certificate you need to copy it to all clients as well. On a Debian system you would do this: : cp Example.com-Root-CA.pem \ : /usr/local/share/ca-certificates/Example.com-Root-CA.crt : update-ca-certificates Note that Debian expects the suffix ".crt" even though the certificate needs to be in PEM format. To check whether the certificate is usable and you have installed GnuPG 2.3 you may use : gpgsm --show-certs /etc/ssl/certsca-certificates.crt | less ** Change RootDN Password: Create temporary file named =passwd.ldif=: #+begin_src dn: olcDatabase={1}mdb,cn=config changetype: modify replace: olcRootPW olcRootPW: XXXX #+end_src For XXXX insert the output of slappasswd and run : ldapmodify -Q -Y EXTERNAL -H ldapi:/// -f passwd.ldif followed by : ldappasswd -x -D cn=admin,dc=example,dc=com -W -S and enter the new and old password again. ** Show ACLs : ldapsearch -Q -Y EXTERNAL -H ldapi:/// -b 'cn=config' olcAccess ** Show a list of databases : ldapsearch -Q -Y EXTERNAL -H ldapi:/// -b 'cn=config' | grep ^olcDatabase: ** Change the log level To debug access problems, it is useful to change the log level: : printf "dn: cn=config\nchangetype: %s\nreplace: %s\n%s: %s\n" \ : modify olcLogLevel olcLogLevel ACL | ldapadd -Q -Y EXTERNAL -H ldapi:/// to revert replace "ACL" by "none". * How to use with Active Directory ** Extending the AD Schema The Active Directory on Windows is actually an LDAP server but configuration differs from OpenLDAP. The used schema is the same but the data objects are slighly different. To extend the schema the LDIF format is used but with variants of the files used for OpenLDAP. Thus please download these two files: - [[https://gnupg.org/misc/gnupg-ldap-ad-schema.ldif]] - [[https://gnupg.org/misc/gnupg-ldap-ad-init.ldif]]. *Important*: Backup your Active Directory before you extend the schema. There are *no ways to revert changes* made to a schema. You should also first try this all on a test system and not on a production system. To extend the schema become Adminstrator on your Primary Domain Controller and open a shell (Command Prompt). Copy the above mentioned ldif files to your working directory and run the following command: : ldifde -i -v -f gnupg-ldap-ad-schema.ldif : -c "DC=EXAMPLEDC" "DC=example,DC=org" This is one line and the last string (="DC=example,DC=org"=) needs to be replaced with your actual domain. If the command succeeds you have extended the schema to store OpenPGP keys at a well known location. The next step is to provide information and space in the tree. This is done similar to the above, namely: : ldifde -i -v -f gnupg-ldap-ad-init.ldif : -c "DC=EXAMPLEDC" "DC=example,DC=org" You may now check your work with ADSI (enter "adsiedit"). Compare with this [[https://gnupg.org/blog/img/ad-with-gnupg-schema.png][screenshot]] and notice the two marked entries. The last step is to setup permissions. This depends on your policy. Here we assume that all authenticated users get read access to all OpenPGP keys and only certain users may insert or update those keys. What you need to do in all cases is to give the group /Everyone/ read access to the =CN=PGPServerInfo= object. This allows the clients to notice that the schema has been installed and where to look further. The actual keys will be stored under =CN=GnuPG Keys=. Thus give all users of the /AuthenticatedUsers/ group read access and use the Advanced button to set /Applies to/ to /This object and all descendant objects/. To insert and update keys, use a group or users and give them permissions for =CN=GnuPG Keys= to /Read/, /Write/, /Create all child objects/, and /Delete all child objects/. As above make sure that these permissions apply to /This object and all descendant objects/. In case you want to access the keys also from non-Windows boxes, it is probably best to created a dedicated guest user for read access. ** Using GnuPG with AD Using the Active Directory is really easy since GnuPG 2.2.26: You only need to put : keyserver ldap:/// into =dirmngr.conf= and Windows takes care of authentication. Note that we use 3 slashes and not ldaps because AD takes care of protecting the traffic. GnuPG can be advised to consult the local AD similar to a Web Key Directory. For this put : auto-key-locate local,ntds,wkd into =gpg.conf= so that a missing key is first looked up in the AD before a WKD query is done. diff --git a/g10/gpg.c b/g10/gpg.c index f3d645d4a..411b6c097 100644 --- a/g10/gpg.c +++ b/g10/gpg.c @@ -1,5708 +1,5708 @@ /* gpg.c - The GnuPG OpenPGP tool * Copyright (C) 1998-2020 Free Software Foundation, Inc. * Copyright (C) 1997-2019 Werner Koch * Copyright (C) 2015-2021 g10 Code GmbH * * This file is part of GnuPG. * * GnuPG is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 3 of the License, or * (at your option) any later version. * * GnuPG is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
