[Freeipa-users] [freeipa-users] How to manage Linux attributes for AD users (e.g. how do I set a shell for an AD User)

[Baird, Josh]

Right, I haven't messed with IDMU in quite some time, so I'm not exactly sure.

Personally, I override using sssd, because all of my users use bash by default.

Hi Josh,

I think that's exactly the problem though, how does one set POSIX attributes in AD from Linux guests?

The RedHat documentation has a big warning that the Microsoft IDMU has been deprecated.

>> https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Windows_Integration_Guide/ex.sssd-ad-posix.html

Surely you're not suggesting manually editing the AD Schema...?

Also, another use case is ssh keys.  I'm not even sure that IDMU has an option for "authorized_keys"  (and FreeIPA doesn't seem to honor what's in .ssh/authorized keys...  when that file exists I always get prompted for a password then access denied).

I'm sure there are other per-user level attributes that are required, home directory perhaps?, but the two big ones are shell and ssh keys.  I can't be the only one who has a use case for managing these attributes for Active Directory users.

Thanks,
Jon A

For AD users, I believe you have two options.

1) Set the POSIX value on the user in AD for the shell
2) Set the following in your client's sssd.conf:

[nss]
override_shell = /bin/bash

This would obviously be global per IPA client.

Hello,

How does one manage linux attributes for AD users.  Primarily in my case, I'm looking to change the default shell to either Bash or KSH depending on the user.

I can create a .profile that either sources bash or ksh rcs... e.g.:

>> $ cat ~/.profile
>> bash ./.bashrc

This is really less than ideal and just seems like the wrong way to do it, especially considering we have a tool like FreeIPA.

According to Microsoft<http://blogs.technet.com/b/activedirectoryua/archive/2015/01/25/identity-management-for-unix-idmu-is-deprecated-in-windows-server.aspx>, they are no longer supporting Identity Management for Unix.  Does FreeIPA honor the attributes set by IDMU?  Even if it's deprecated, I suppose we could continue to use it...
This previous FreeIPA thread<https://www.redhat.com/archives/freeipa-users/2013-April/msg00007.html> seems to indicate you can force the shell for anyone in the domain logging into that machine, but we have some users who prefer one shell over the other.

I did what I believe to be standard, I created a security group in AD, added that group to a group an external group in FreeIPA, then made an internal group and added the external group as a member to the internal group.  Unfortunately, this doesn't seem to expose any of the AD attributes for management.  Or maybe I'm just misunderstanding...

Any thoughts?  How are you managing individual AD user settings?

Thanks,
Jon A
