+Subject: [PATCH] krb5: disable Kerberos localauth an2ln plugin for AD/IPA
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If a client is joined to AD or IPA SSSD's localauth plugin can handle
+the mapping of Kerberos principals to local accounts. In case it cannot
+map the Kerberos principals libkrb5 is currently configured to fall back
+to the default localauth plugins 'default', 'rule', 'names',
+'auth_to_local', 'k5login' and 'an2ln' (see man krb5.conf for details).
+All plugins except 'an2ln' require some explicit configuration by either
+the administrator or the local user. To avoid some unexpected mapping is
+done by the 'an2ln' plugin this patch disables it in the configuration
+snippets for SSSD's localauth plugin.
+
+Resolves: https://github.com/SSSD/sssd/issues/8021
+
+:relnote: After startup SSSD already creates a Kerberos configuration
+ snippet typically in /var/lib/sss/pubconf/krb5.include.d/localauth_plugin
+ if the AD or IPA providers are used. This enables SSSD's localauth plugin.
+ Starting with this release the an2ln plugin is disabled in the
+ configuration snippet as well. If this file or its content are included in
+ the Kerberos configuration it will fix CVE-2025-11561.
