PAM-SCRIPT(7)						 Miscellaneous Information Manual					     PAM-SCRIPT(7)

NAME
pam-script - a PAM module that can invoke scripts within the PAM stack. SYNOPSIS
pam-script.so [onerr=(success|fail)][dir=/some/path/] DESCRIPTION
pam-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 in pam.conf sshd auth required pam_script 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. OPTIONS
A summary of options is included below. onerr=(success|fail) the default behavior if the module can not find or execute the script. The default is to fail if the option is not given. dir=/some/path/ where to find the pam-scripts to invoke for each of the various module-types as described below. The default is dir=/usr/share/lib- pam-script if not given. List of scripts pam_script_auth Executed under auth which handles the authentication stage of establishing the user via some challenge-response (i.e. username/pass- word) pam_script_acct invoked under account module-type for non-authentication based account management. pam_script_passwd invoked under passwd for changing the password tokens. pam_script_ses_open invoked when a session is first opened. pam_script_ses_close run after a session 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. FILES
/lib/security/pam_script.so - the PAM module /usr/share/libpam-script - where the scripts should be placed by default VERSION
