Bug: GSSAPI: Unexpected NUL in auth data

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 auth

The bug appears to have been introduced by this patch:


Should mech_gssapi also have the MECH_SEC_ALLOW_NULS flag set?

Kind regards,
