Re: GSSAPI Authentication

[Dennis Putnam]

Hi Viktor, You are correct, it was indeed SMTP. I thought about that but I can't find any references to it in the Postfx documentation. Where do I look to specify that? If it simply uses mit.edu.Kerberos, that file is correct. It may be that it can't find that file but again I don't see where to specify a path for it. Thanks.

When I try to send mail, I get this error in the log: warning: SASL authentication failure: GSSAPI Error: Unspecified GSS failure.  Minor code may provide more information (Key table entry not found) You have eliminated the most important part of this error message: the name of the complaining process. We can guess that it was "smtpd", as we expect the SMTP server to use keytabs, and the SMTP client to use a credential cache. The error indicates that "smtp/<servername>@REALM" was not found in the keytab file used. Make sure you are using the right keytab file and that it has the expected contents. -- Viktor.
