Dovecot 2.3.11.3 added extra safety checks in its SASL implementation, and broke GSSAPI authentication doing so. The auth process appears to just hang, only in debug mode it says:

dovecot[1197686]: auth: Debug: gssapi(?,2a06:f00::,<foo>): Unexpected NUL in auth data

This is fixed in Dovecot git; please backport commit fea1bacab954d2f112da8a95756f198530e274af to fix the issue.
