My OES2 SP1 server all of a sudden stopped working with NRM.

I can no longer login as root nor as admin to NRM on this server.

I get a "Username or password is invalid"

I've restarted the httpsk, I've restarted namcd

iMangler works fine (but I think that uses diff. information)

admin IS in the LUM configuration (but then again I've had other OES2 servers where the correct users were in LUM and stuff still didn't work properly)
