On some DB2/2 2.x servers (running OS/2 Wapr 4), I often get a UPM 2227
error message from MUGLIB when trying to perform a logon

NERR_ACFNotLoaded : The user account system has not been started.

But how do I start this user account system? I tried several exe's in
the \MUGLIB directory, to no avail.
