Bug: GSSAPI: Unexpected NUL in auth data
Hi,
After upgrading server to v2.3.11.3 (Arch linux). I can no longer connect from Evolution client to the server via GSSAPI (Kerberos). I get the following message in the log:
auth: Debug: gssapi(?,x.x.x.x,<XXX>): Unexpected NUL in authdata
The bug appears to have been introduced by this patch:
https://github.com/dovecot/core/commit/d196f4c83c7383c17440d39eb994b4cd9ff5a...
Should mech_gssapi also have the MECH_SEC_ALLOW_NULS flag set?
Kind regards,
Paul
