Please excuse me if this was already answered but after I went trhough the archives I coulnd't find anyone facing the same issue, please bear with me as I'm a newbie to FreeIPA and LDAP. I know I'm missing something or doing it wrong but after a week struggling with this setup I decided to call for the help of the experts. My environment: FreeIPA Server CentOS 6.5 x86_64 Mail Server CentOS 6.5 postfix-2.6.6-6.el6_5.x86_64 dovecot-2.0.9-7.el6.x86_64 ipa-python-3.0.0-37.el6.x86_64 ipa-client-3.0.0-37.el6.x86_64 python-iniparse-0.3.1-2.1.el6.noarch libipa_hbac-1.9.2-129.el6_5.4.x86_64 libipa_hbac-python-1.9.2-129.el6_5.4.x86_64 I've followed these posts from Dale McCartney, whom I've also read his posts around here <a class="moz-txt-link-freetext" href="https://www.dalemacartney.com/2013/03/14/deploying-postfix-with-ldap-freeipa-virtual-aliases-and-kerberos-authentication/">https://www.dalemacartney.com/2013/03/14/deploying-postfix-with-ldap-freeipa-virtual-aliases-and-kerberos-authentication/</a> <a class="moz-txt-link-freetext" href="http://www.freeipa.org/page/Dovecot_Integration">http://www.freeipa.org/page/Dovecot_Integration</a> None of them seem to work at the moment when using Thunderbird with the server set up as STARTLS Kerberos/GSSAPI -- Thunderbird also reports that <quote> "The kerberos/GSSAPI ticket was not accepted by the IMAP server <a class="moz-txt-link-abbreviated" href="mailto:david@domain.com">david@domain.com</a>. Please chack that you're logged in to the Kerberos/GSSAPI realm" </quote> with Dovecot I'm getting this <code> Jun 22 11:01:25 imap-login: Info: Disconnected: Inactivity (no auth attempts): rip=1.1.1.1, lip=217.1.2.3 </code> I tried manual telnet and use a authenticate gssapi which retuns "+" which means module is indeed loading and the server is gssapi ready for the challenge. If anyone of you could point me into the right direction I'd really value that. Thanks --- Regards David G. </body> </html>
