GSSAPI Error

[Paul S. <psc...@gm...>]

Hello:

I'm attempting to authenticate using kerberos and GSSAPI via SASL. Whenever
I attempt to fetch my mail, I get the following error:

IMAP command 'AUTHENTICATE GSSAPI' returned an error: NO AUTHENTICATE
failed.

I built isync v1.2.1 from source. Happy to provide any other details to
help debug.

Thanks
Paul
