Environment:* Linux 64-bit community edition
* MongoDB 2.5.5 sharded cluster with CR authentication enabled on admin database of mongoS and admin database per shard.
* MongoClient connection made to multiple mongoSes via a URI:
"mongodb://admin:admin@mms-db1:60000,mms-db1:60001,mms-db2:60000,mms-db2:60001/"
* 2.12.0 snapshot build jar at:

MongoClient exposes a method `isLocked()` that checks if the given node is fsync locked.
On 2.5.5 via a mongoS, this operation fails with the following exception:
com.mongodb.MongoException: DBClientBase::findN: transport error: mms-db1:50000 ns: admin.$cmd.sys.inprog query: { $query: {} }

Note:
- The command was given to a mongoS listed in the URI mentioned in Environment above.
- The mms-db1:50000 from the trace is the primary of the first shard.
In the mms-db1:50000's mongod.log, the following message is logged:
[conn551] AssertionException handling request, closing client connection: 16810 bad query: BadValue unknown top level operator: $query
It appears to be dependent on going through the mongoS, but unclear if auth-enabled is a factor.
