Groups in ldap and /etc/group?

Hi Mike,

Thank you for your response.

It makes sense to me.
And your solution is exactly as I have done it so far.

However, there still is one problem to be solved.

When I have defined the groups I wish to use for Samba in the ldap database,
then I still need to know how to handle existing (unix) users.
When my passd backend is the ldap database, I will have to add them in there
too (for their password), right?
But when I do this, they are assigned a new uid and gid number.

I can't figure out how to solve this. The user has to be in ldap for his
ntpasswd, home directory, profile directory, etc.
Is the only option to add a new username for samba purposes only?
