       auth-client-config - pam and NSS profile switcher


       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.


       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]


              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.


       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:

         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:

         nss_passwd=passwd: files
         nss_group=group: files
         nss_shadow=shadow: files
         nss_netgroup=netgroup: nis
         pam_auth=auth    required nullok_secure debug
         pam_account=account required debug
         pam_password=password   required nullok obscure \
           min=4 max=8 md5 debug
         pam_session=session required debug
                session optional

       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


       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


       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.
