this worked for me now..it seems like to me issue with Identity Appliance coz i had integrated vCAC appliance with vSphere SSO 5.5u1c coupled with vCenter Server. This made me login to the vCAC with my Active Directory credentials and i am no more seeing certificate mismatch error.

Only error logged into catalina.out log file is that while i am performing look-up for usernames to be granted different privileges in vCAC via SSO,

vcac: [component="cafe:identity" priority="INFO" thread="tomcat-http--36" tenant="vsphere.local"] com.vmware.vcac.authentication.service.sso.impl.PrincipalManagementImpl.findPersonUsers:79 - Can't call findPersonUsersByName, reason class[class com.vmware.vim.sso.admin.exception.InternalError], fall back to findPersonUsers

i checked Release notes for any difference in SSO for vCAC and SSO for vCenter but could not notice significant difference which could tell me difference in versions of SSO being used.

i am however able to fetch user profile despite of these errors.
