NAMEsssd_krb5_localauth_plugin − Kerberos local authorization plugin

DESCRIPTIONThe 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​.

CONFIGURATIONThe 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 directory​. If this directory is included in the local Kerberos configuration the plugin will be enabled automatically​.
