Authentication problem [message #132920] Fri, 18 November 2016 10:46

we're using Kerio connect 9.1.1 (1433)on Debian GNU/Linux 7.9, x86_64.

Since yesterday authenticating users using Active Directory worked fine.

Now some users can login with strange delay or sometimes no connection, and others cannot login.
Connection test on Kerio Admin portal it's ok. I've not changed anything on Kerio configuration.

I can't find Kerberos configuration file (krb5.conf)

If on Domain Controller I disable "Do not require Kerberos preauthentication" on Active Directory Users and Computers > Account it works normal as before.

But with this configuration we can potentionally have security problems.

The only thing we've done is demote and delete a Domain Controller, other two DC are up and running.

Any suggestion is appreciated.
