[Samba] Managing Samba Active directory.

Replying back to the list :-)

The Sudoers functionality is achieved by modifing the Samba schema, the sudo package itself distributes the schema change LDIF:

$ rpm -ql sudo | grep schema

Technically if you could find the correct schema to store autofs data in AD then it should work.

Red Hat even appear to allow you to specify the LDAP attributes and object classes to use:


In fact, someone's already got Samba 4 serving automount data:

Hmm, thanks to all who replied... you've actually made me think of 
another question... I gues it's a bit odd on this list to see someone 
who's looking at using AD that doesn't know anything about it... last 
time I was tempted down the Windows path it was Win9x.

Anyway, you mentioned "netgroup management", which makes me wonder if 
the other NIS style maps can be hosted in AD, such as autofs maps.. is 
there any guide for how to do that.

I guess it's a shame there's no native GUI for doing this since 
Microsoft's directory management stuff does seem to be rather ubiquitous 
and perhaps if it can support all the maps we would want in Unix then we 
could leverage that...

The ADUC tools are also very useful for visualising your LDAP tree and moving things around. Our internal documentation also says you need to use the ADUC tools to add UNIX Attributes to a Security Group. There might be a way to do it on the command line but none of us have seemed to have bothered to figure it out :-)
> I would recommend a single Windows Server (2012) with the ADUC tools installed for management (you could probably get by with Win8.1 but Server is less "graphical"). The server just needs to be joined to your domain, it doesn't need to be DC as well. Then just install the "AD Management Tools" role and you should be set.
> I do not recommend other Linux based LDAP management tools, eg: LAM (https://www.ldap-account-manager.org/lamcms/). Our staff are under strict instructions only to use LAM for Netgroup management. You can create users and groups in LAM that badly break things on the AD side, like not creating the correct password expiry attributes.
