[Handle-info] Failure to replicate mirror handle server 7.3.1 from primary handle 6.2.5 server

I have a mirror server setup with Handle 7.3.1 against the primary Handle 6.2.5 server.

Followed the instructions to configure the mirror "6.1 Setting up a Single Mirror Handle Server"

from http://www.handle.net/tech_manual/Handle_Tech_Manual_7_v1-1-22Dec10.pdf

The replication fails with the following error:

Has anybody successfully done this?

I suspect that the error might be caused by this change from 7.3 release notes:

"Signature code now uses algorithm DSAwithSHA1 instead of just DSA."

Any ideas how I can force 7.3.1 to use DSA instead of DSAwithSHA1?
