Need more details here.

What is the imap server name ?

Check the KDC logs do you see the client asking for a ticket ? Is it
successful ?

Withouth any data I am using my crystal ball and thinking the most
probably cause is that you are using a different name in the client than
what you configured your IMAP server's keytab with.

This is because I guess the client copuldn't get a ticket so it didn't
even attempt authentication.
