Hello everyone, I am hoping someone can help me with a problem.
I have a Samba4 AD domain. I have dovecot setup to do gssapi against this AD. I have postfix configured to use dovecot sasl. It works great for imap in windows and linux. In Windows, smtp doesn't work for gssapi, but works for plain and login (which are configured along with gssapi in dovecot). These are all Thunderbird. With Windows I get the following: postfix/smtpd[6364]: warning: CLIENT_FQDN[CLIENT_IP]: request longer than 2048: AUTH GSSAPI gssapidata. My query is this: does postfix truncate or otherwise mess up the data when the above warning is given? If not, has anyone seen something similar? Is it a bug in Thunderbird? I imagine the reason Kerberos is larger in Windows than Linux is the PAC. Some of you may have seen other posts elsewhere which state I have fixed this and it was related to S4 not setting userPrincipalName correctly for a service principal. This is what got Linux Thunderbird working, but not Windows. Any help anyone can offer would be GREATLY appreciated. Thank you, Trever Adams -- "Black holes are where God divided by zero." -- Unknown
