adenroll: set password via LDAP instead Kerberos
Use LDAP add/mod operation instead of Kerberos to set the machine account password.
There was an issue in AD where if PacRequestorEnforcement was set to '2' setting the machine account password via Kerberos would be rejected. This is already fixed on the AD side bit this patch which was created with the help of David Mulder dmulder@suse.com might still be useful if setting the machine account password with Kerberos might fail.
