Given an Atlassian Crowd server with either its internal user database
or some other backend user management system (e.g. LDAP), this utility
makes it possible to establish a single-sign-on environment for Linux
systems whereby users can log into Linux systems with the same password
they use against other Crowd backed systems.
When a user attempts to log into a Linux system running crowd_pam.py,
the username is verified against Crowd and if the user exists in Crowd,
a corresponding local Linux user account will be created. Then if the
user's username and password pass authentication, the user will be
allowed to sign into the system.
If the user is a member of groups in Crowd that do not exist on the
local Linux machine, crowd_pam.py will create the groups on the local
Linux system. If a user is removed from a group membership on Crowd,
he/she will be removed from the user group on the local Linux system.
