pam_unix_account - PAM account management module for UNIX SYNOPSIS
pam_unix_account.so.1 DESCRIPTION
pam_unix_account module implements pam_sm_acct_mgmt(), which provides functionality to the PAM account management stack. The module pro- vides functions to validate that the user's account is not locked or expired and that the user's password does not need to be changed. The module retrieves account information from the configured databases in nsswitch.conf(4). The following options can be passed to the module: debug syslog(3C) debugging information at the LOG_DEBUG level nowarn Turn off warning messages server_policy If the account authority for the user, as specified by PAM_USER, is a server, do not apply the Unix policy from the passwd entry in the name service switch. ERRORS
The following values are returned: PAM_UNIX_ACCOUNT User account has expired PAM_AUTHTOK_EXPIRED Password expired and no longer usable PAM_BUF_ERR Memory buffer error PAM_IGNORE Ignore module, not participating in result PAM_NEW_AUTHTOK_REQD Obtain new authentication token from the user PAM_PERM_DENIED The account is locked or has been inactive for too long PAM_SERVICE_ERR Error in underlying service module PAM_SUCCESS The account is valid for use at this time PAM_USER_UNKNOWN No account is present for the user ATTRIBUTES
