Joining Ubuntu to AD

Hello Everyone

Iam getting the following error when i tried to join the ubuntu client to my univention domain. Please find the Attached Snap’s.

I have fixed the above issue by changing my /etc/resolv.config. I have added my univention server DNS in resolv.conf file.

Now I am facing another Problem.

I am trying to integrate the ubuntu to ucs Ad from the following document

In ths Document i have completed the following topics

  1. Integration into the LDAP directory and the SSL certificate authority

  2. Configuration of the System Security Services Daemon (SSSD)

  3. Configuring user logins

  4. Kerberos integration

When Iam trying to Login It was showing Error Like Invalid Credentials
