Hi Werner,

I am running Fedora 20 and here is some information regarding the the installed
packages

Name : gnupg
Arch : x86_64
Version : 1.4.19
Release : 2.fc20

Name : openldap
Arch : x86_64
Version : 2.4.39
Release : 4.fc20

I didn't compile any of them from source. I downgraded gnupg but for some reason
it went to 1.4.15

Name : gnupg
Arch : x86_64
Version : 1.4.15
Release : 1.fc20

This version works without a problem. Then upgrading again causes the problem to
come back.

Regarding the ldap setup, I followed the approach given in

Please let me know if you need any further information.

Thanks
