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
environment 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
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
system cache name
-c file, --config-file=file
