+|===
+|Description
+a|Sets the default permission mask applied to the Unix Domain Socket file. This mask should be set as restrictive as possible (especially when authentication is disabled on this connector).Note, however, that this permission may not be honored by Posix systems other than Linux.
+|Valid values
+a|A set of file permissions.
