Verify users against Active Directory on Linux

[Jonas Back_2]

We have lots of Linuxservers running Red Hat 7.3 and 8.0. They all have local users and each user have an individual password on each server.

We also have a Active Directory. Any suggestions on solutions how to verify users against the Active Directory instead of a local user on each Linux?

All thoughts and exepriences welcome.

there are many docs and tutorials, see http://yolinux.com/TUTORIALS/LinuxTutorialLDAP.html for example, but I didn't try it.

Hello!

You can start to use the NIS (yp - yellow pages commands)
This is checked for years and many people use
it for problem like your.
The NIS it's easy to configure.
You have the NIS server (master and slaves)
and you have NIS clients.
Use the ypinit, check in man.
In the end you will have one file for all
the network that will use the NIS,
for you is like one passwd file for everyone.

Hi ,

I strongly recommend using open-ldap on a linux server. It is much more secure than NIS, and it also scales better.

Ldap can even be used authenticate in microft networks.

Asing authconfig on the client side, makes setting up ldap on the clients a dream.
See http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/ref-guide/ch-ldap.html for further information.
