"RM" is Resource Manager, like TORQUE or PBSPro.
maui clients have a built-in seed to hash the requests for
authentication, so all maui clients and server that need to talk to each
must have the same seed.
If you don't specify a seed at build-time, configure picks a random
number. Are your maui clients from the same build as your server? Did
you specify a seed?
