Like EC2132, except that in this case the user ID matches, and the primary group ID requested by emake is available to that user, but one or more supplementary group IDs requested by emake is not available to that user on an agent node.
See also EC2133, which is for an unavailable primary group ID.
See Summary above.
A supplementary group available to the emake client is not available to the same user on an agent node.
Either grant membership in the group on all agent nodes, or deny membership on the emake client.
