2.- Is it a local system, a VM or a cloud one?
3.- Have you installed all the packages in step 1?
4.- Please provide the content of file /etc/sssd/conf.d/00-sssd.conf .
5.- Show permissions and owner for file /etc/sssd/conf.d/00-sssd.conf:

Sorry, my mistake I forgot to add this manually.

[student@localhost pam.d]$ cat common-session
session required pam_unix.so
session optional pam_oddjob_mkhomedir.so
session optional pam_sss.soi
[student@localhost pam.d]$

the issue is still present.

One update I want to add the lab is working on ubuntu 20.04.

luisviveropena

Hi @vikrantchaudhary21, thanks for informing us that the lab worked for you on Ubuntu 20.04. I'm checking on CentOS 8 Stream. I'll let you know as soon as I have news.

Regards,
Luis.

Hi @vikrantchaudhary21,

This lab is guaranteed to work on Ubuntu 20.04 and is optional. What you have learned here is that each Linux distro handles some tools differently and tool configuration for one distro may not work for other distros. Getting LDAP to work on anything else other than Ubuntu 20.04 is up to the student.

We will make sure of adding a note to this lab.

Many regards,
Luis.
