sssd_krb5_locator_plugin - the configuration file for SSSD
The Kerberos locator plugin sssd_krb5_locator_plugin is used by the
Kerberos provider of sssd(8) to tell the Kerberos libraries what Realm
and which KDC to use. Typically this is done in krb5.conf(5) which is
always read by the Kerberos libraries. To simplyfy the configuration
the Realm and the KDC can be defined in sssd.conf(5) as described in
sssd(8) puts the Realm and the name or IP address of the KDC into the
enviroment variables SSSD_KRB5_REALM and SSSD_KRB5_KDC respectively.
When sssd_krb5_locator_plugin is called by the kerberos libraries it
reads and evaluates these variable and returns them to the libraries.
Not all Kerberos implementations support the use of plugins. If
sssd_krb5_locator_plugin is not available on your system you have to
edit /etc/krb5.conf to reflect your Kerberos setup.
If the enviroment variable SSSD_KRB5_LOCATOR_DEBUG is set to any value
debug messages will be sent to stderr.
