[Fedora-directory-users] FDS <-> AD: UID/GID and OU sync

[Alex Davies]

Hi All,

We have an AD architecture setup, and are looking to sync FDS with
this to allow us to authenticate Linux machines and network devices.

We have two AD domains, and have a winsync and passsync setup with one
of the domain controllers in each domain. This works, subject to the
limitation that we have to manually create each OU. Once we create the
OU in FDS, the users appear at the next sync. Question 1: is it
possible to automatically sync *all* OU's, including creating the OU
in FDS if it does not exist? We have hundreds of OUs, and I don't want
to have to create them all manually.

Question 2 is on UNIX UID/GID sync from AD. I've found a couple of
posts which imply that it is not possible to sync UID/GUD from AD[1],
but this was some time ago. An alternative piece of documentation
suggests that it is, but provides no details[2]. I'm also struggling
to find documentation on the libdna plugin, which I believe is
involved[3].

My questions are
- Is it possible to sync UID/GID from AD (where AD has the Unix Tools
installed, and therefore has these attributes in the schema).
- Is it possible to automatically apply a unique UID/GID to each user
that does not have a UID/GID?

Any help/pointers greatly appreciated.

Many thanks,

Alex

The cvs head now contains a new feature for automatic generation of
sequenced numbers which is compatible with multi-master replication
environments. This feature can be used for automatic generation of
posix uidNumber and gidNumber in addition to other sequenced numeric
attributes required by your deployment. "

Not sure.  But I suppose it could be scripted if the init AD sync 
process does not create them.

That is correct.

It just says that you can have the
directory server automatically assign 
uidNumber and gidNumber.  It doesn't say anything about AD sync.

We're working on it.

No, not yet.  We have to add support for the posix schema to our AD sync 
mechanism.  This is on the roadmap.

Not after the fact.  You'll have to write a script to do that.

Many thanks for your replies Rich! I look forward to those features appearing...

For records, maybe you can use my perl scripts for that.

First for search all OU's automatically in a MS ADS:

Once imported the list of OU's, the users can be imported into FDS and
create uid/gid automatically with:
