installing new idm servers (idm 4.6.1, edir 9.0.3.1) into an existing tree
(idm 4.0.2, edir 8.8.4). i migrated (in designer) an existing driverset to the
new server. errors there, but the driverset ist listed as 'running' on both.

choosing the new server in imanager 'identity manager overview' | <driverset> |
'Servers' | choose the other server in the drop-down-list results in error -603.

the dirxml-trace shows:
10:00:39 1F10 DirXML: ENG EV: Unable to get schema ID for attribute
'DirXML-UseNoRefAssoc': failed, no such attribute (-603)
10:00:39 1F10 DirXML: ENG EV: Unable to get schema ID for attribute
'DirXML-AssociationsLite': failed, no such attribute (-603)
10:00:39 1F10 DirXML: ENG EV: Unable to get schema ID for attribute
'DirXML-CacheLocation': failed, no such attribute (-603)

this is correct - those attributes are not in my schema, but found nothing
in the documentation of a schema extension. the .sch files coming with 4.6 also
have no such attributes listed ..

have a missed out something along the way?

thanks for your input, florian
