[Samba] net sam/samba ldap: Failed to add user 'xxx' with error: Group already exists.

[Steven Enderle]

Hello,

we are trying to set up Samba with LDAP Backend. Using the Samba
toolchain to add our existing users/groups, the net command seems to get
confused about what users and groups are, if both have the same name and
are used in the same context.

Here is what I tried:

==commandline==
-> Create the Domain Group
# net sam createdomaingroup duplicate -U Administrator%pwd
Created domain group duplicate with RID 1172

-> Create the User
# net rpc user add duplicate -U Administrator%pwd
Failed to add user 'duplicate' with error: Group already exists.

Other way around, adding first user then group, similar result:

-> Create the User
# net rpc user add duplicate2 -U Administrator%pwd
Added user 'duplicate2'.

-> Create the Domain Group
# net sam createdomaingroup duplicate2 -U Administrator%pwd
Created domain group duplicate2 with RID 1174

-> Add new User to Group
# net sam addmem duplicate2 duplicate2 -U Administrator%pwd
Can only add members to local groups so far, duplicate2 is a User
==commandline==

Samba seems to fail at differentiating groups and users of same name.

1) Is there a way to tell samba/net to add the user duplicate to group
duplicate?

2) Is there a dirty workaround that will get us running anyway?

3) What is the background that causes this problem? Is there something I
am missing?

Thanks for your help in advance.
