Exception while getting JCo connection error

Hi ,

I have recently changed SLD for Portal 7.0 system.

In content admin, even the SLD connection test is working fine.

Now there is a problem with Jc0 connections.

Only the SSO -Jco connection test is getting successful but the metadata Jco connection fails with the error"

why the username/password Jco only fails.

the backend system is exist in the new sld as technical system with all logon groups

I will appreciate your help

Thanks in advance
