PAM_SELINUX_PERMIT(8) Linux-PAM Manual PAM_SELINUX_PERMIT(8) NAME pam_selinux_permit - PAM module to allow/deny login depending on SELinux enforcement state SYNOPSIS pam_selinux_permit.so [debug] [conf=/path/to/config/file] DESCRIPTION The pam_selinux_permit module allows or denies login depending on SELinux enforcement state. When the user which is logging in matches an entry in the config file he is allowed access only when the SELinux is in enforcing mode. Otherwise he is denied access. For users not matching any entry in the config file the pam_selinux_permit module returns PAM_IGNORE return value. The config file contains a simple list of user names one per line. If the name is prefixed with @ character it means that all users in the group name match. If it is prefixed with a % character the SELinux user is used to match against the name instead of the account name. Note that when SELinux is disabled the SELinux user assigned to the account cannot be determined. This means that such entries are never matched when SELinux is disabled and pam_selinux_permit will return PAM_IGNORE. Each user name in the configuration file can have optional arguments separated by : character. The only currently recognized argument is exclusive. The pam_selinux_permit module will allow only single concurrent user session for the user with this argument specified and it will attempt to kill all processes of the user after logout. OPTIONS debug Turns on debugging via syslog(3). conf=/path/to/config/file Path to alternative config file overriding the default. MODULE SERVICES PROVIDED Only the auth and account services are supported. RETURN VALUES PAM_AUTH_ERR SELinux is disabled or in the permissive mode and the user matches. PAM_SUCCESS SELinux is in the enforcing mode and the user matches. PAM_IGNORE The user does not match any entry in the config file. PAM_USER_UNKNOWN The module was unable to determine the user?s name. PAM_SERVICE_ERR Error during reading or parsing the config file.
