Calendar clients 4.03 cannot work offline since we have upgraded to Calendar Server 4.0

Question

Macintosh Calendar 4.03 cannot work offline since I have upgraded to Calendar Server
version 4.0. When users attempt to either go offline or login offline,
they receive module errors:
<P>
Module:>CApplicationCorporateTime.cp>,
Label:20, Service error#(0x1320a)
<P>
It looks like versions 4.03 and lower clients (primarily on the Macintosh) are unable to
properly handle data from the 4.0 Server as it was able to in the 3.5 server.
<P>
There have been changes made with the new 4.0 server version as to how a
password is sent over the network to the client. In order for a customer to
use an old client version (pre 4.5) with the offline agenda, the following
parameter needs to be set in the server's /users/unison/misc/unison.ini file:
<P>
[ENG]
pwdreturnonitemget = TRUE
<P>
Once all users have been upgraded to client version 4.5x or higher, it is
highly recommended to remove this parameter or to set it to the
default value FALSE.
This parameter becomes active as new client sessions are established. It is
not necessary to stop and start the server.
<P>
The best solution for this issue is to only use Calendar client versions 4.5
or higher.
