The solution:

The license manager that Sun uses with their compilers comes from
Globetrotter Software ( With versions
2 and 3 of the compilers, Sun used version 2.61 or so; with version
4 of the compilers Sun went to version 4 of Globetrotter's license
manager. I was still using version 2.61 of lmgrd, and that version
does not know about any form of name service other than NIS.

Most of you probably have seen the CERT advisory that recently came
out about the security problems in lmgrd versions 5.0a and earlier
(based upon the AUSCERT advisory of around September or so -- I wonder
why it took CERT 3 months to propogate it to this side of the Pacific).

My solution was to upgrade my license manager to version 5.0b by
obtaining the latest & greatest directly from Globetrotter Software.
The latest version is available free from their web server. They also
provide instructions on how to run your license manager under a non-root
user, which I also did and recommend to others (it is quite easy).
I am now able to use the compilers from any NIS/DNS domain in the company.

for forwarding me the entire Globetrotter FAQ on lmgrd plus the
text of the AUSCERT identifying the security holes in lmgrd versions
5.0a and earlier.
