SSSD_KRB5_LOCALAUTH_(8) SSSD Manual pages SSSD_KRB5_LOCALAUTH_(8) NAME sssd_krb5_localauth_plugin - Kerberos local authorization plugin DESCRIPTION The Kerberos local authorization plugin sssd_krb5_localauth_plugin 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. 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. 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. CONFIGURATION The Kerberos local authorization plugin must be enabled explicitly in the Kerberos configuration, see krb5.conf(5). SSSD will create a config snippet with the content like e.g. [plugins] localauth = { module = sssd:/usr/lib64/sssd/modules/sssd_krb5_localauth_plugin.so } automatically in the SSSD's public Kerberos configuration snippet direc- tory. If this directory is included in the local Kerberos configuration the plugin will be enabled automatically.
