My Configuration
i have 3 servers
Server1 - OSP , SSPR , UA
OSP & SSPR running on tomcat
UA on Websphere

UA of server1 is configured to be redirected to OSP of the server1 and
vice versa

Server2 - OSP , SSPR , UA
OSP & SSPR running on tomcat
UA on Websphere

UA of server2 is configured to be redirected to OSP of the server2 and
vice versa

Server3 - OSP , SSPR , UA
OSP & SSPR running on tomcat
UA on Websphere
UA of server3 is configured to be redirected to OSP of the server3 and
vice versa

all the 3 servers are in a cluster in Websphere

the 3 servers are not clustered in tomcat

no my issue is when i am accessing the IDMprov application of Server1 ,
some times i am redirected to OSP of server 2 and server3 and getting
the error

Error: An invalid OAuth2 request was received.

I checked in the Osp trace and i find the below error message

Text: Client "redirect_uri" did not validate against registered urls!

I rechecked all my redirect URL's , everything is correct , but i am not
able to understand 1 thing that when i am accessing UA on Server1 , y it
is redirecting me to OSP of another server

Please provide your valuable suggestions

I will be using a load balancer , but i want each server to work individually

Also how can i ensure fail over here

Thanks in advance
