admin-roles appears to be ignored and allegedly privileged users cannot execute methods appropriately

Connecting as admin, I am able to execute this command string to see the group(s) to which pnittel belongs:

c=getGroupsForUser( "pnittel"); for (cb:c)

{ print( cb.getName() ); }

Connecting as pnittel, I cannot execute that same command. pnittel is a member of the itgroup and that group is assigned all three roles. I'm attaching deploy.properties and admin-roles.properties.

Here's the dialog:
admin $ connectAsAdmin("pnittel","mm","mm://localhost:31000");
conn-1[mm://localhost:31000] $ c=getGroupsForUser( "pnittel"); for (cb:c) { print( cb.getName() ); }
