auth-client-config:(8)
NAME
auth-client-config - pam and NSS profile switcher
DESCRIPTION
This program updates nsswitch.conf and pam configuration files to aid
in authentication configuration. If the existing nsswitch.conf and pam
system configuration does not exist in the profiles database,
auth-client-config will comment out the current configuration in such a
way that the changes can be undone by auth-client-config with the -r
option.
USAGE
auth-client-config -p PROFILE -a -t TYPE [-dn -f FILE]
auth-client-config -p PROFILE -a -t TYPE -r [-n -f FILE]
auth-client-config -p PROFILE -a -t TYPE -s [-f FILE]
OPTIONS
- --version
- show program's version number and exit
- -h, --help
- show this help message and exit
- -a, --all-types
- apply all types for specified profile
- -d, --database-only
- update file(s) only if current entries are in database
- -f FILE, --file=FILE
- update FILE instead of default
- -l, --list-profiles
- list available profiles
- -L, --list-types
- list available types
- -n, --dry-run
- don't modify anything, just show the changes
- -p PROFILE, --profile=PROFILE (required)
- use PROFILE
- -r, --reset
- reset file(s) to previous non-auth-client-config values. Will not remove the current entries unless they match PROFILE
- -s, --check-system
- determine if system files are set to PROFILE
- -S, --show-system
- show current system settings as a profile
- -t TYPE, --type=TYPE
- modify files for TYPE. Multiple types can be specified with a comma separated list.
PROFILES DATABASE
Each time auth-client-config is run, it will check the profiles database (by default, /etc/auth-client-config/profile.d) for authentication
profiles. Files may be added to the profiles database directory to
support custom authentication configurations. This is useful for a
distribution maintainer to have his/her authentication package put an
authentication profile into the profiles database, and then have
his/her package use auth-client-config to update the system configuration. It also allows for an administrator to set up a single profile
for site-wide network authentication roll-outs.
- The files in the profiles database use the .INI configuration file
standard, and the syntax is:
- [example]
nss_passwd=nsswitch.conf entry for 'passwd'
nss_group=nsswitch.conf entry for 'group
nss_shadow=nsswitch.conf entry for 'shadow'
nss_netgroup=nsswitch.conf entry for 'netgroup'
pam_auth=pam entry/entries for 'auth'
pam_account=pam entry/entries for 'account'
pam_password=pam entry/entries for 'password'
pam_session=pam entry/entries for 'session' - If you need to specify multiple entries for a specific type (which is often the case with PAM), then simply list additional entries on a newline preceded by a tab. For example, an entry for local configuration might be:
[example_local]
nss_passwd=passwd: files
nss_group=group: files
nss_shadow=shadow: files
nss_netgroup=netgroup: nis
pam_auth=auth required pam_unix.so nullok_secure debug
pam_account=account required pam_unix.so debug
pam_password=password required pam_unix.so nullok obscure \min=4 max=8 md5 debug- pam_session=session required pam_unix.so debug
session optional pam_foreground.so
- Notice how in the above, pam_session has two entries (pam_password in this example should be all on one line, hence the '\').
- To use the above entry with auth-client-config, create a file with the above entries in it and put the file into the profiles database directory (typically named after the profile or package that added it). Now call auth-client-config with:
auth-client-config -a -p example_local
EXAMPLES
- Set nsswitch.conf and pam to use the 'example_local' profile:
- auth-client-config -a -p example_local
- Set only nsswitch.conf to use the 'example_local' profile, but only if current nsswitch.conf entries exist in the profiles database:
- auth-client-config -t nss -p example_local -d
- Restore nsswitch.conf and pam to previous non-auth-client-config files:
- auth-client-config -a -p example_local -r
KNOWN ISSUES
If two or more profiles have the same name, only the last one will be
used. Additionally, if a profile in the profiles database has more
than one entry for a particular field (eg, two 'nss_passwd' entries),
then then the last one read will be used.
auth-client-config strips out all carriage returns when run on Unix.
