samba - Sep 2005 - net rpc group add mygroup - NT_STATUS_ACCESS_DENIED

does not work.

Hi - I'm a little bit desperated.

I've samba configured as an PDC with openldap as an information backend. 
Normally with tdb files I can do the command

net rpc group add mygroup

and this works. But if I switch to ldapsam I get the failure message

root@balu-bash(1:10)# net rpc group add mygroup
Password:
add group failed: NT_STATUS_ACCESS_DENIED

I'm quite sure that the permissions are correctly set, and the password 
is also ok. The new group will be found in /etc/group but not in the 
ldaptree.

I debugged everything with logfiles and strace but I can't find the 
reason. Any consideration would be great.

tnx

- Thomas
