pam-script - a PAM module that can invoke scripts within the PAM stack.
DESCRIPTIONpam-script allows you to execute scripts during authorization, passwd changes, and on session opening or closing.
Such scripts can perform necessary tasks or influence the outcome of
the PAM stack. For example, if the following entry was included
then if the script, pam_script_auth, exits with a non-zero value this would cause the user to be denied SSH access to the machine.
OPTIONSA summary of options is included below.
- the default behavior if the module can not find or execute the script. The default is to fail if the option is not given.
where to find the pam-scripts to invoke for each of the various
module-types as described below.
The default is dir=/etc if not given.
List of scripts
- Executed under auth which handles the authentication stage of establishing the user via some challenge-response (i.e. username/password)
- invoked under account module-type for non-authentication based account management.
- invoked under passwd for changing the password tokens.
- invoked when a session is first opened.
run after a
is first closed.
All the scripts will be passed several environment variables: PAM_USER, PAM_RUSER, PAM_RHOST, PAM_SERVICE, PAM_AUTHTOK, PAM_TTY, and PAM_TYPE referring to the module-type. The pam_script.so arguments in the pam.conf will be passed on the command line, which can be used to modify the script behavior.
