.SH "NAME"
sssd_krb5_localauth_plugin \- Kerberos local authorization plugin
.SH "DESCRIPTION"
.PP
The Kerberos local authorization plugin
\fBsssd_krb5_localauth_plugin\fR
is used by libkrb5 to either find the local name for a given Kerberos principal or to check if a given local name and a given Kerberos principal relate to each other\&.
.PP
SSSD handles the local names for users from a remote source and can read the Kerberos user principal name from the remote source as well\&. With this information SSSD can easily handle the mappings mentioned above even if the local name and the Kerberos principal differ considerably\&.
.PP
Additionally with the information read from the remote source SSSD can help to prevent unexpected or unwanted mappings in case the user part of the Kerberos principal accidentally corresponds to a local name of a different user\&. By default libkrb5 might just strip the realm part of the Kerberos principal to get the local name which would lead to wrong mappings in this case\&.
.SH "CONFIGURATION"
.PP
The Kerberos local authorization plugin must be enabled explicitly in the Kerberos configuration, see
\fBkrb5.conf\fR(5)\&. SSSD will create a config snippet with the content like e\&.g\&.
.sp
.if n \{\
.RS 4
.\}
.nf
[plugins]
 localauth = {
  module = sssd:/usr/lib64/sssd/modules/sssd_krb5_localauth_plugin\&.so
 }
.fi
.if n \{\
.RE
.\}
.sp
automatically in the SSSD\*(Aqs public Kerberos configuration snippet directory\&. If this directory is included in the local Kerberos configuration the plugin will be enabled automatically\&.
