Hi Aaron, we've just identified this problem and thought you may be interested if you haven't resolved this already. The bind is failing because the admin account being used to join the domain is a member of too many groups (waiting to hear from M$ what constitutes too many) and as a result the Kerberos TGT is too large and the kpasswd service on the M$ DC just ignores the change password request. To work around this created an admin account with minimal group membership and use this to bind Samba boxes to AD. Of course you may have a different issue with M$ ;-) cheers Andy. Thanks all. At least now I know it's not just me. I'll be watching bugzilla with interest, and in the meantime I suppose standard Kerb will have to do.
