pam_usertype -- check if the authenticated user is a system or regular account
--------------------------------------------------------------------------
DESCRIPTION
pam_usertype.so is designed to succeed or fail authentication based on
type of the account of the authenticated user. The type of the account is
decided with help of SYS_UID_MAX settings in /etc/login.defs. One use is
to select whether to load other modules based on this test.
The module should be given only one condition as module argument.
Authentication will succeed only if the condition is met.
OPTIONS
The following flags are supported:
use_uid
Evaluate conditions using the account of the user whose UID the
application is running under instead of the user being
authenticated.
audit
Log unknown users to the system log.
Available conditions are:
issystem
Succeed if the user is a system user.
isregular
Succeed if the user is a regular user.
EXAMPLES
Skip remaining modules if the user is a system user:
account sufficient pam_usertype.so issystem
