Note: Earlier versions of DAL were referred to as CL/1.
There is a compatibility problem with the new VMS 5.4 release and the CL/1 1.0 and 1.1 VAX/VMS servers. Due to changes in VMS password authentification in VMS 5.4, AppleTalk connections fail when made to the earlier versions of VAX/VMS Server (CL/1 Servers 1.0 and 1.1) running on a VMS 5.4 system. This is a problem with AppleTalk connections only; asynchronous connections do work. There is no workaround for the 1.0 and 1.1 versions.
DAL 1.2 is compatible with VAX/VMS 5.1 through 5.3. Compatibility with VAX/VMS 5.4 is shown below.
