Conceptually, yes.
In the PAM world, authorization checks such as this are done as part of the 
"authenticate" operation, not the "account management" operation.

For cases where authentication is not done using PAM, such as sshd using 
gssapi user auth, the application is responsible for performing whatever 
authorization checks are required.  In ssh, this is done as part of the 
user authentication operation.
