NAME
     kcm -- process-based credential cache for Kerberos tickets.

SYNOPSIS
     kcm [--cache-name=cachename] [-c file | --config-file=file] [-g group |
         --group=group] [--max-request=size] [--disallow-getting-krbtgt]
         [--detach] [-h | --help] [-k principal |
         --system-principal=principal] [-l time | --lifetime=time] [-m mode |
         --mode=mode] [-n | --no-name-constraints] [-r time |
         --renewable-life=time] [-s path | --socket-path=path]
         [--door-path=path] [-S principal | --server=principal] [-t keytab |
         --keytab=keytab] [-u user | --user=user] [-v | --version]

DESCRIPTION
     kcm is a process based credential cache.  To use it, set the KRB5CCNAME
     enviroment variable to `KCM:uid' or add the stanza


     [libdefaults]
             default_cc_name = KCM:%{uid}

     to the /etc/krb5.conf configuration file and make sure kcm is started in
     the system startup files.

     The kcm daemon can hold the credentials for all users in the system.
     Access control is done with Unix-like permissions.  The daemon checks the
     access on all operations based on the uid and gid of the user.  The tick-
     ets are renewed as long as is permitted by the KDC's policy.

     The kcm daemon can also keep a SYSTEM credential that server processes
     can use to access services.  One example of usage might be an nss_ldap
     module that quickly needs to get credentials and doesn't want to renew
     the ticket itself.

     Supported options:

     --cache-name=cachename
             system cache name

     -g group, --group=group
             system cache group

     -k principal, --system-principal=principal
             system principal name

     -l time, --lifetime=time
             lifetime of system tickets

     -m mode, --mode=mode
             octal mode of system cache

     -n, --no-name-constraints
