Samba share mode database library external interface library.
Used by non-Samba products needing access to the Samba share mode db.
+ NOTICE FOR SAMBA 4.2.0
+
+ THIS CODE IS NON-FUNCTIONAL IN SAMBA 4.2.0 AND ABOVE DUE TO THE CHANGES IN
+ SHARE MODE DATABASE SCHEMA FOR SMB2 LEASES.
+
+ CONTACT THE AUTHOR jra@samba.org IF YOU WISH TO RE-ENABLE
