+/* This auth module is very similar to auth_winbind with 3 distinct
+ * differences.
+ *
+ *      1) Does not fallback to another auth module if winbindd is unavailable
+ *      2) Does not validate the domain of the user
+ *      3) Handles unencrypted passwords
+ *
+ * The purpose of this module is to defer all authentication decisions (ie:
+ * local user vs NIS vs LDAP vs AD; encrypted vs plaintext) to the wbc
+ * compatible daemon.  This centeralizes all authentication decisions to a
+ * single provider.
+ *
+ * This auth backend is most useful when used in conjunction with pdb_wbc_sam.
