6 sssd_krb5_localauth_plugin - Kerberos local authorization plugin
7
9 The Kerberos local authorization plugin sssd_krb5_localauth_plugin is
10 used by libkrb5 to either find the local name for a given Kerberos
11 principal or to check if a given local name and a given Kerberos
12 principal relate to each other.
13
14 SSSD handles the local names for users from a remote source and can
15 read the Kerberos user principal name from the remote source as well.
16 With this information SSSD can easily handle the mappings mentioned
17 above even if the local name and the Kerberos principal differ
18 considerably.
19
20 Additionally with the information read from the remote source SSSD can
21 help to prevent unexpected or unwanted mappings in case the user part
22 of the Kerberos principal accidentally corresponds to a local name of a
23 different user. By default libkrb5 might just strip the realm part of
24 the Kerberos principal to get the local name which would lead to wrong
25 mappings in this case.
26
28 The Kerberos local authorization plugin must be enabled explicitly in
29 the Kerberos configuration, see krb5.conf(5). SSSD will create a config
30 snippet with the content like e.g.
31
32 [plugins]
33 localauth = {
34 module = sssd:/usr/lib64/sssd/modules/sssd_krb5_localauth_plugin.so
35 }
36
37 automatically in the SSSD's public Kerberos configuration snippet
38 directory. If this directory is included in the local Kerberos
39 configuration the plugin will be enabled automatically.
