SPNEGO problem with Firefox 2.0.0.3 on Mac OS 10.4.9

[Siarhei Baidun]

Hi folks,
recently I've faced up with the problem of using SPNEGO with Firefox on Mac
OS

Firefox version: 2.0.0.3
Mac OS version: 10.4.9

Firefox sends not SPNEGO token but KRB_AP_REQ token instead (which is in
fact should have been mechToken)

Firefox configuration:
network.negotiate-auth.allow-proxies=true
network.negotiate-auth.delegation-uris=http://
network.negotiate-auth.gsslib=
network.negotiate-auth.trusted-uris=http://
network.negotiate-auth.using-native-gsslib=true

Attached is ASN1 structure of "SPNEGO" token that is sent by Firefox

BTW Safari (2.0.4) works fine without any additional configuration.

Does anybody have a clue how to fix?
