[Samba] Warning in logs: gid of user does not exist

[Andrea Venturoli]

Hello.
I've setup a FreeBSD 4.x machine with Samba 2.x and and OpenLDAP backend.
I recently upgraded to Samba 3.0.10 and put "passdb 
backend=ldapsam_compat" in smb.conf.

Now, everythings seems to work all right, but I see a lot of this 
entries in the logs:

Feb 17 19:42:27 xxxxx smbd[44170]:   get_alias_user_groups: gid of user 
yyyyyyy
doesn't exist. Check your /etc/passwd and /etc/group files

This happens always with yyyyyy ever changing and being either an user 
or machine account.

I can't get to understand the reasons of this: /etc/passwd and 
/etc/group are correct.

In OpenLDAP I only have user/machine accounts, not groups.

I tried "net group [add]" but it does nothing. Also "net groupmap list" 
shows no entries, which I don't think is correct.

I've read all the howto and googled a lot, but found no answer.
Any hint?

  bye & Thanks
