ok, I did a simple GSSAPI test on the client with ldapsearch using
"ldapsearch -Y GSSAPI" and I get "Server not found in Kerberos database".
In log.samba on the server, it gives:
Kerberos: TGS-REQ user @ MYDOMAIN.NET from ipv4:10.45.1.55:48879 for ldap/
ubuntu-test.mydomain.net @ MYDOMAIN.NET [renewable, proxiable, forwardable]
Kerberos: Server not found in database: ldap/ubuntu-test.mydomain.net @
MYDOMAIN.NET: no such entry found in hdb
Kerberos: Failed building TGS-REP to ipv4:10.45.1.55:48879
I have added "ldap/ubuntu-test.mydomain.net @ MYDOMAIN.NET" into the
server's /etc/krb5.keytab file using ktutil but the error still comes up.
It is as if Kerberos is not checking
