Comment 55 for bug 305264

I guess we are having the same problem authenticating against a sun open directory server. I use intrepid-proposed on my client:

root@client:~# dpkg-query -W -f='${Package} ${Version} ${Source} ${Status}\n' | egrep 'slapd|ldap|gnutls'
gnutls-bin 2.4.1-1ubuntu0.3 gnutls26 install ok installed
ldap-auth-client 0.5.2 install ok installed
ldap-auth-config 0.5.2 ldap-auth-client install ok installed
ldap-utils 2.4.11-0ubuntu6.2 openldap install ok installed
libcurl3-gnutls 7.18.2-1ubuntu4.3 curl install ok installed
libgnutls26 2.4.1-1ubuntu0.3 gnutls26 install ok installed
libldap-2.4-2 2.4.11-0ubuntu6.2 openldap install ok installed
libnss-ldap 260-1ubuntu2 install ok installed
libpam-ldap 184-4ubuntu2 install ok installed

The rest is attached:
ldap.conf
output of gnutls-cli -p636 --x509cafile CAFILE srv.obf.obf.ob
output of ldapsearch -x -ZZ -d7

If you need anything else, please ask.
