OSF released DCE 1.0, including
all the DCE components described above, in 1992. In addition to
specifications, OSF delivered a reference implementation to vendors. By 1993, the first DCE implementations
were available. A partial list of current DCE vendors includes:
AT&T
Bull
DEC
Gradient
Technologies
Hitachi
HP
IBM
Pyramid
SCO
Siemens
Nixdorf
SGI
Stratus
Tandem
Transarc
OSF released DCE 1.1 to vendors
late in 1994, and vendors are expected to release their implementations by
mid-1995. DCE 1.1 provides for enhanced auditing and the X/Open-approved GSSAPI and Extended
Registry Attributes (ERA). These will permit enterprises to bring non-DCE domains under the DCE security
umbrella for common enterprise-wide security administration.
OSF expects to release DCE 1.2
to vendors in two phases: DCE 1.2.1 in November of 1995 and DCE 1.2.2 in
July of 1996. The primary theme for this release will be to remove obstacles to broad end-user deployment
of DCE. The focus areas for this release are currently administration, ease of programming, support
for
legacy systems, scalability, security, and DFS enhancements.
While DCE continues to evolve,
a number of large end-user organizations have committed to basing their
next- generation, enterprise-wide information systems on DCE.
