A question of DB2 authentication

[huyuhui]

Please see the following question:

AUTHENTICATION=SERVER_ENCRYPT allows DB2 to encrypt which of the
following?
A.data
B.userid
C.password
D.userid and password

Answer:D

I choose C as correct answer. When we set AUTHENTICATION to
SERVER_ENCRYPT, DB2 only encrypt the password. That's my opinion.

Anybody can tell me why the answer is D, not C.

Thanks.

Your answer C should be correct - according to the online information
center. The following is from the V9 (and V8) online information center:

If authentication is SERVER, the user ID and password are sent from the
client to the server so that authentication can take place on the
server. The value SERVER_ENCRYPT provides the same behavior as SERVER,
except that any passwords sent over the network are encrypted.

Either the given answer is wrong or the manual needs updating.
