pam_dce(5) pam_dce(5) NAME
pam_dce - authentication, account, and password management PAM functions for DCE SYNOPSIS
/usr/lib/security/libpam_dce.so.1 DESCRIPTION
The DCE PAM modules allow integration of DCE into the system entry services (such as login, telnet, rlogin, ftp) through the pam.conf(4) file. The DCE service module for PAM consists of the following three modules: the authentication module, the account management module, and the password management module. All three modules are supported through the same loadable library, /usr/lib/security/libpam_dce.so.1 is the interface that services the requests from These requests will be communicated to the DCE security server, which in turn sends the response back to ilogind. This response is then sent back to /usr/lib/security/libpam_dce.so.1. Authentication Module The authentication module certifies the identity of a user and the user's credentials. It passes the authentication key derived from the user's password to the DCE Security Service. The Security Service then uses the authentication key to certify the user and the user's cre- dentials. The following options can be passed to the authentication module through the pam.conf(4) file: debug Turn on syslog debugging at the LOG_DEBUG level. nowarn Turn off warning messages about not being able to acquire DCE credentials. use_first_pass Use the initial password (entered when the user is authenticated to the first authentication module in the stack) to authenticate with DCE. If the user can not be authenticated or if this is the first authentication module in the stack, quit and do not prompt a password. It is recommended that this option be used only if the authentication mod- ule is designated as optional in the pam.conf(4) configuration file. try_first_pass Use the initial password (entered when the user is authenticated to the first authentication module in the PAM stack) to authenticate with DCE. If the user cannot be authenticated or if this is the first authentication module in the stack, prompt for a password. A user must be authenticated and the user's credentials set before a system entry service can access any file directories owned by the user that are mounted through DTS. Account Management Module The account management module provides a function to perform account management (pam_sm_acct_mgmt(3)). sends a request to the DCE implementation of pam_sm_acct_mgmt(3) function which retrieves the user's account and password expiration information from the DCE Security Server and verifies that the user's account and password have not expired. The following options can be passed to the account module through the pam.conf(4) file: debug Turn on syslog debugging at the LOG_DEBUG level. nowarn Turn off warning messages displayed when a user's account and/or password are going to expire. pam_sm_acct_mgmt(3) calls the function sec_login_inquire_net_info(3) to retrieve information about when a user's account and/or password is going to expire. Password Management Module The password management module provides a function to change passwords (pam_sm_chauthtok(3)). The following options can be passed to the password module through the pam.conf(4) file: debug Turn on syslog debugging at the LOG_DEBUG level. nowarn Turn off warning messages about not being able to change passwords. try_first_pass Use the initial password (entered to the first password module in the PAM stack) to authenticate with DCE. If the user cannot be authenticated or if this is the first password module in the stack, prompt for a password. use_first_pass Use the initial password (entered to the first password module in the PAM stack) to authenticate with DCE. If user cannot be authenticated or if this is the first password module in the stack, quit and do not prompt for a password. It is recommended that this option be used only if the DCE password module is designated as optional in the pam.conf(4) configuration file. SEE ALSO
