Is UsePAM set in your sshd_config ?

     UsePAM  Enables the Pluggable Authentication Module interface.  If set
             to "yes" this will enable PAM authentication using
             ChallengeResponseAuthentication and PAM account and session mod-
             ule processing for all authentication types.

             Because PAM challenge-response authentication usually serves an
             equivalent role to password authentication, you should disable
             either PasswordAuthentication or
             ChallengeResponseAuthentication.

             If UsePAM is enabled, you will not be able to run sshd(8) as a
             non-root user.  The default is "no".

Will.
