NAME
pam_user.conf - user configuration file for pluggable authentication modules
SYNOPSIS
DESCRIPTION
is the user configuration file for the Pluggable Authentication Module architecture, or PAM. It is not designed to replace the PAM system
configuration file, For PAM to work properly, is mandatory (see pam.conf(4)). is optional. It is used only when a user basis configura-
tion is needed. It mainly specifies options to be used by service modules on a user basis.
The options defined in indicate the default for users who are not configured in or if the module type is not configured for some users.
For the configuration in to take effect, needs to configure service module (see pam.conf(4)).
Simplified pam_user.conf Configuration File
The file contains a listing of login names. Each login name is paired with a corresponding service module with or without options speci-
fied. Each entry has the following format:
login_name module_type module_path options
Below is an example of the configuration file.
tom auth /usr/lib/security/$ISA/libpam_unix.so.1 debug use_psd
tom auth /usr/lib/security/$ISA/libpam_dce.so.1 use_first_pass
tom account /usr/lib/security/$ISA/libpam_unix.so.1 use_psd
tom account /usr/lib/security/$ISA/libpam_dce.so.1 try_first_pass
susan auth /usr/lib/security/$ISA/libpam_unix.so.1
susan auth /usr/lib/security/$ISA/libpam_dce.so.1 try_first_pass
The login_name denotes the login name of a user (for example, For detailed information on module_type, module_path, and options, see
pam.conf(4).
The first entry indicates that when the UNIX authentication is invoked for the options and will be used. The second entry indicates that
when the DCE authentication is invoked for the option will be used. The module type is not configured for therefore, the options will take
effect. For those users who are not configured, the options apply.
Notes
If an error is found in an entry due to invalid login_name or module_type, then the entry is ignored. If there are no valid entries for
the given module_type, the PAM framework ignores and reads the configuration in
EXAMPLES
The following is a sample configuration file. Lines that begin with the symbol are treated as comments, and therefore ignored.
