.Dt PAM.CONF 5
.Os
.Sh NAME
.Nm pam.conf
.Nd Pluggable Authentication Modules configuration file
.Sh DESCRIPTION
The
.Nm
file specifies how Pluggable Authentication Modules
.Pq PAM
should operate.
For an overfiew of the Pluggable Authentication Modules framework, see
.Xr pam 8 .
.Pp
PAM may be configured using a single
.Pa /etc/pam.conf
configuration file or by using multiple configuration files, one for each
PAM-aware service, located in the
.Pa /etc/pam.d/
directory.
If
.Pa /etc/pam.d/
exists,
.Pa /etc/pam.conf
will be ignored.
.Pa /etc/pam.d/
is the preferred method for configuring PAM.
.Pp
PAM's configuration is based on
.Dq stacking
different modules together to form a processing chain for the task.
A standard PAM configuration stanza is structured as follows:
.Bd -offset indent
.Op Ar service-name
.Ar module-type
.Ar control-flag
.Ar module-name
.Op Ar options
.Ed
.Pp
.Ar service-name
is used only
.Pq and is mandatory
in
.Pa /etc/pam.conf .
It specifies the PAM-aware service whose PAM behavior is being configured.
When
.Pa /etc/pam.d/
is used, the name of the configuration file specifies the service.
.Pp
.Ar module-type
specifies which of the four classes of PAM module functionality is being
configured.
These four classes are
.Em account
.Pq account management ,
.Em auth
.Pq authentication ,
.Em password
.Pq password management ,
and
.Em session
.Pq session management .
.Pp
.Ar control-flag
speficies the behavior of the processing chain upon success or failure
of the PAM module's authentication task.
The following are valid values for
.Ar control-flag :
.Bl -tag -width sufficient
.It requisite
If the module returns success, continue to execute the processing chain.
If the module fails, immediately return the error code from the first
.Sq required
failure.
.It required
If the module returns success, continue to execute the processing chain.
If the module fails, record as a
.Sq required
failure and continue to execute the processing chain.
If there are any
.Sq required
failures in the processing chain, the chain will ultimately return
failure.
.It optional
If the module returns success, continue to execute the processing chain.
If the module fails, record as an
.Sq optional
failure and continue to execute the processing chain.
.It sufficient
If the module returns success and there have been no recorded
.Sq required
failures, immediately return success without calling any subsequent
modules in the processing chain.
If the module fails, return as an
.Sq optional
failure and continue to execute the processing chain.
.El
.Pp
.Ar module-name
specifies the module to execute for this stanza.
This is either an absolute path name or a path name relative to the
default module location:
.Pa /usr/lib/security .
.Pp
.Ar options
are additional options that may be specified for the module.
Refer to the individual modules' docuementation for more information
on available options.
.Pp
In addition to the standard configuration stanza format, there an additional
stanza format availble when
.Pa /etc/pam.d/
is in use:
.Bd -offset indent
.Ar module-type
include
.Ar service-name
.Ed
.Pp
This stanza format provides a simple inheritance model for processing
chains.

.El
.Sh EXAMPLES
The following
.Em auth
processing chain for the
.Dq login
service
.Po
located in
.Pa /etc/pam.d/login
.Pc
performs the following tasks: allows the login if the old user
and new user are the same, verifies that logins are not disabled using
the
.Pa /var/run/nologin
file, allows Kerberos 5 password authentication, and requires standard
.Ux
password authentication if Kerberos 5 failed:
.Bd -literal
auth sufficient pam_self.so
auth required pam_nologin.so
auth sufficient pam_krb5.so
auth required pam_unix.so
