pam_usertype8Linux-PAMpam_usertypecheck if the authenticated user is a system or regular accountpam_usertype.soflagconditionDESCRIPTION
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_MIN and 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.
