NMAS authentication errors out with -1644. 1644 errors are normal when a authentication has timed out, however in this case the 1644 returns as soon as the nmas login happens, instead of 3 minutes later.  This issue appears to be only happen on Linux/Unix servers. NetWare is not effected.

In DSTRACE, NMAS uses a session count from 0 to 63, after which is should reuse a session number, if it is available. In this case, every 64th bind (same session number each time) would fail with a 1644 error.


Apply Security Services 2.0.4 (or greater)
