.Sh DESCRIPTION
|
|||
|
|
.Nm
|
|||
|
|
is a process based credential cache.
|
|||
|
|
To use it, set the
|
|||
|
|
.Ev KRB5CCNAME
|
|||
|
|
enviroment variable to
|
|||
|
|
.Ql KCM: Ns Ar uid
|
|||
|
|
or add the stanza
|
|||
|
|
.Bd -literal
|
|||
|
|
|
|||
|
|
[libdefaults]
|
|||
|
|
default_cc_name = KCM:%{uid}
|
|||
|
|
|
|||
|
|
.Ed
|
|||
|
|
to the
|
|||
|
|
.Pa /etc/krb5.conf
|
|||
|
|
configuration file and make sure
|
|||
|
|
.Nm kcm
|
|||
|
|
is started in the system startup files.
|
|||
|
|
.Pp
|
|||
|
|
The
|
|||
|
|
.Nm
|
|||
|
|
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.
|
|||
|
|
.Pp
|
|||
|
|
The
|
|||
|
|
.Nm
|
|||
|
|
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.
