+Subject: [PATCH] upstream: Fix multiple RFC 4462 (GSSAPIAuthentication)
+ compliance
+
+problems
+
+1) Remove an early failure return for GSSAPI authentication attempts
+made for invalid accounts that yielded different behaviour for
+valid vs invalid accounts.
+
+2) Fix a situation where some GSSAPI requestes were not correctly
+subjected to MaxAuthTries.
+
+3) Fix a moderate pre-authentication resource DoS related to #2.
+
+Add missing logging for error cases.
+
+Report and fixes from Manfred Kaiser, milCERT AT
