We are facing an issue with SSO when using the load balancer URL, however it works when we use the actual server URL.
The environment is
BO 4.1 SP5 FP3
2 Application Servers + 2 Tomcat Web Servers + CISCO H/W Load balancer
We have also checked whether there is any duplicate SPN (using setspn -X) but there is nothing. Looks like all the necesary SPNs are created. When we enabled the kerberos trace in the client machine, we could see the below error
A Kerberos Error Message was received:
Error Code: 0x19 KDC_ERR_PREAUTH_REQUIRED
Has anyone faced the similar issue?
