+
+=over 4
+
+=item C<dbconnect [%params]>
+
+Establishes a new database connection to the database configured for
+C<$self>. Returns a database handle as returned by
+L<SL::DBConnect/connect> (which is either a normal L<DBI> handle or
+one handled by L<DBIx::Log4perl>).
+
+C<%params> are optional parameters passed as the fourth argument to
+L<SL::DBConnect/connect>. They're first filtered through
+L<SL::DBConnect/get_options> so the UTF-8 flag will be set properly.
+
+=item C<ensure_webdav_symlink_correctness>
+
+Handles the symlink creation/deletion for the WebDAV folder. Does
+nothing if WebDAV is not enabled in the configuration.
+
+For each existing client a symbolic link should exist in the directory
+C<webdav/links> pointing to the actual WebDAV directory which is the
+client's database ID.
+
+The symbolic link's name is the client's name sanitized a bit. It's
+calculated by L</webdav_symlink_basename>.
+
+=item C<get_dbconnect_args [%params]>
+
+Returns an array of database connection parameters suitable for
+passing to L<SL::DBConnect/connect>.
+
+C<%params> are optional parameters passed as the fourth argument to
+L<SL::DBConnect/connect>. They're first filtered through

+
+=item C<validate>
+
+Returns an array of human-readable error messages if the object must
+not be saved and an empty list if nothing's wrong.
+
+=item C<webdav_symlink_basename>
+
+Returns the base name of the symbolic link for the WebDAV C<links>
+sub-folder.
