Hey,
Hope to find some solution.
just now I started my 23rd attempted :-))
Situation in my Lab is reallyyyy strange..
check this out..
I did not update STS service with root-trust.jks. (if i do SSOB will not install)
soo, the credentials is same while updating service endpoint..
STS endpoint got updated successfully,
Admin and GroupCheck is giving Invalid Credentials. Error.
5.1 is full of BedBugs. :-))
