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 en-
     vironment 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.   Ac-
     cess control is done with Unix-like permissions.  The daemon checks the ac-
     cess  on  all operations based on the uid and gid of the user.  The tickets
     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.

     --cache-name=cachename
