Has anyone on the list set up such as scheme for adding posix attributes to users synced from AD, and would like to comment on this approach? I'm thinking that maybe running a cron job (for example a couple of times an hour) that searches for newly added users, then using "ldapmodify" to add the required posix attributes, may be the way to go.That might work. There is some documentation about how to poll Active Directory for changes to entries:
http://msdn.microsoft.com/en-us/library/ms677626(VS.85).aspx and http://support.microsoft.com/kb/891995I have a python-ldap script that implements support for the DirSync control - http://github.com/richm/scripts/tree/master/dirsyncctrl.py

Yes you understood me correctly - I ment it doesn't seem like Windows Sync is intended for Linux machine login (via SSH to be precise) to "just work" with no additional work. I'm sorry that I wasn't too clear on this. Is it so that one usually has a AD/DS setup like this: * users/passwords are synced from AD to DS * the new users are exported to ldif file, added things such as posix attributes, and reimported into DS * users can now log into linux servers (via SSH) that are properly configured as LDAP clients ? Just trying to get an understanding of how one usualy set up AD and DS to work together. I think that's how it usually goes. Perhaps some other folks that are doing this will chime in. freeIPA will soon have support for automatic creation of AD user accounts in IPA, including all of the posix and kerberos attributes needed for OS login.

I'm not sure what you mean by that. Do you mean because the posix attributes are not synced, you cannot create a user in AD that is synced to Fedora DS and Linux machine login "just works" with no additional work? It is possible to get this working, however, through a series of manual steps. So what is the intended purpose for Windows Sync, if I might ask, as it seems a lot simpler just to manage everything directly from DS without syncing with AD? I think most people use it to sync passwords, so that you can have the same password on AD as Unix/Linux, and when you change the password on one side, that change is synced to the other side.

But note that posix attributes will not sync to AD. And even if you did manage to find a posix schema that worked with AD, and added the posix schema on the AD side, those attributes would not be synced to Fedora DS.Thanks for your answer.I start to wonder if Windows sync is worth the trouble. At my site we will probably not implement password sync as the AD-side is very restrictive about installing anything. I hear this all the time - AD admins are very touchy about installing anything, especially some piece of random open source software that's going to intercept clear text passwords and send them who-knows-where So what I get is basically a skeleton that I have to populate with the posixUser attributes. Another issue is groups in AD. I suppose those groups will become regular unix-groups on the directory server side, Yes. But note - not posix groups (posixGroup) but plain groups (groupOfUniqueNames) which might not be enough for all policing needs (may need netgroups in addition). Sure. We will probably have maximum a few hundred users in the directory, do you think Windows-sync is worth the bother?
