AUTHCONFIG(8) System Manager's Manual AUTHCONFIG(8)
NAME
authconfig, authconfig-tui - an interface for configuring system authentication resources
SYNOPSIS
authconfig
[options] {--update|--updateall|--test|--probe|--restorebackup <name>|--savebackup <name>|--restorelastbackup}
DESCRIPTION
authconfig provides a simple method of configuring /etc/sysconfig/network to handle NIS, as well as /etc/passwd and /etc/shadow, the files
used for shadow password support. Basic LDAP, Kerberos 5, and Winbind client configuration is also provided.
If --test action is specified, the authconfig just reads the current settings from the various configuration files and prints their values.
If --update action is specified, authconfig must be run by root (or through console helper), and configuration changes are saved. Only the
files affected by the configuration changes are overwritten. If --updateall action is specified, authconfig must be run by root (or
through console helper), and all configuration files are written. The --probe action instructs authconfig to use DNS and other means to
guess at configuration information for the current host, print its guesses if it finds them, to standard output, and exit.
The --restorebackup, --savebackup, and --restorelastbackup actions provide a possibility to save and later restore a backup of configura-
tion files which authconfig modifies. Authconfig also saves an automatic backup of configuration files before every configuration change.
This special backup can be restored by the --restorelastbackup action.
If --nostart is specified (which is what the install program does), ypbind or other daemons will not be started or stopped immediately fol-
lowing program execution, but only enabled to start or stop at boot time.
The --enablenis, --enableldap, --enablewinbind, and --enablehesiod options are used to configure user information services in /etc/nss-
witch.conf, the --enablecache option is used to configure naming services caching, and the --enableshadow, --enableldapauth, --enablekrb5,
and --enablewinbindauth options are used to configure authentication functions via /etc/pam.d/system-auth. Each --enable has a matching
--disable option that disables the service if it is already enabled. The respective services have parameters which configure their server
names etc.
The algorithm used for storing new password hashes can be specified by the --passalgo option which takes one of the following possible val-
ues as a parameter: descrypt, bigcrypt, md5, sha256, and sha512.
The --enablelocauthorize option allows to bypass checking network authentication services for authorization and the --enablesysnetauth
allows authentication of system accounts (with uid < 500) by these services.
When the configuration settings allow use of SSSD for user information services and authentication, SSSD will be automatically used instead
of the legacy services and the SSSD configuration will be set up so there is a default domain populated with the settings required to con-
nect the services. The --enablesssd and --enablesssdauth options force adding SSSD to /etc/nsswitch.conf and /etc/pam.d/system-auth, but
they do not set up the domain in the SSSD configuration files. The SSSD configuration has to be set up manually. The allowed configuration
of services for SSSD are: LDAP for user information (--enableldap) and either LDAP (--enableldapauth), or Kerberos (--enablekrb5) for
authentication.
In case SSSD does not support some feature of the legacy services that are required for the site configuration, the use of the legacy ser-
vices can be forced by setting FORCELEGACY=yes in /etc/sysconfig/authconfig.
The list of options mentioned here in the manual page is not exhaustive, please refer to authconfig --help for the complete list of the
options.
The authconfig-tui supports all options of authconfig but it implies --update as the default action. Its window contains a Cancel button by
default. If --back option is specified at run time, a Back button is presented instead. If --kickstart is specified, no interactive screens
will be seen. The values the program will use will be those specified by the other options (--passalgo, --enableshadow, etc.).
For namelist you may substitute either a single name or a comma-separated list of names.
NOTES
The authconfig-tui is deprecated. No new configuration settings will be supported by its text user interface. Use system-config-authentica-
tion GUI application or the command line options instead.
The /usr/bin/authconfig uses the consolehelper to authenticate as the system user before it starts up. If you want to run it directly with-
out the authentication as the system user, run the /usr/sbin/authconfig command.
RETURN CODES
authconfig returns 0 on success, 1 on backup operation errors, 2 if not running with sufficient privileges, 3 if unknown password hash
algorithm is specified or incorrect values are set for password strength checking (this error is non fatal), 4 if download of CA certifi-
cate fails, 5 if writing configuration files fails on --updateall action, 6 if writing fails on --update action, 7 if Winbind or IPA domain
join fails.
authconfig-tui returns 0 on success, 2 on error, and 1 if the user cancelled the program (by using either the Cancel or Back button). It
can also return the same codes as authconfig.
FILES
/etc/sysconfig/authconfig
Used to track whether or not particular authentication mechanisms are enabled. Currently includes variables named USESHADOW,
USEMD5, USEKERBEROS, USELDAPAUTH, USESMBAUTH, USEWINBIND, USEWINBINDAUTH, USEHESIOD, USENIS, USELDAP, and others.
/etc/passwd
/etc/shadow
Used for shadow password support.
/etc/yp.conf
Configuration file for NIS support.
/etc/sysconfig/network
Another configuration file for NIS support.
/etc/ldap.conf
/etc/nss_ldap.conf
/etc/pam_ldap.conf
/etc/nslcd.conf
/etc/openldap/ldap.conf
Used to configure nss_ldap, pam_ldap, nslcd, and the OpenLDAP library. Only the files already existing on the system are modified.
/etc/krb5.conf
Used to configure Kerberos 5.
/etc/hesiod.conf
Used to configure Hesiod.
/etc/samba/smb.conf
Used to configure winbind authentication.
/etc/nsswitch.conf
Used to configure user information services.
/etc/login.defs
Used to configure parameters of user accounts (minimum UID of a regular user, password hashing algorithm).
/etc/pam.d/system-auth
Common PAM configuration for system services which include it using the include directive. It is created as symlink and not relinked
if it points to another file.
/etc/pam.d/system-auth-ac
Contains the actual PAM configuration for system services and is the default target of the /etc/pam.d/system-auth symlink. If a
local configuration of PAM is created (and symlinked from system-auth file) this file can be included there.
