      Encountered against Amazon SSL 64-bit 2.7.7-pre build from this morning. (at commit 986d4a410e).

      When authSchemaVersion=4 is used together with --setParameter authenticationMechanisms=SCRAM-SHA-1, authentication on the shell always fails, even when explicitly specifying the mechanism.

      For example:

      > use admin
> db.auth({user:"admin", pwd:"foo", mechanism:"SCRAM-SHA-1"})
Error: 18 Authentication failed.
0

      The server log contains the following message on each failed attempt when specifying the mechanism:

      2014-09-19T20:36:57.602+0000 I ACCESS   [conn4] SCRAM-SHA-1 authentication failed for admin on admin ; BadValue Illegal value for authorization data schema version, 4
