user accounts + addressbook?

[rdeman]

hi all,

im experimenting with openldap. I found great tutorials on how to use
openldap for authentication for projects such as subversion, trac,
etc. Also I found great tutorials on hwo to setup addressbooks in
openldap for use with Thunderbird etc.

but I cannot find any info or how-to's on the combination of these
two. How do I configure openldap in such a way that I can simply
create a group of 'users' and those 'users' all have login name,
password, shell, etc AND stuff like Firstname, Lastname, Phone, email,
Company, etc?
And then finally just order them into groups: So that I can simply
have a 'user' that is either just a record in the addressbook, but
might also have access to one or more projects (I want to setup a
group for each project, so that ldap membership (user aliases?) to a
group means that the user also access to the project associated by
that group)

Is this porrible? Any help?
