Thanks Vlado.
While I checked this option as well, I am not able to connect eclipse to HCP yet.
Initially I thought deleting SAP passport installed in browser might help, but it did not.
Then I reset S-user password to make sure I am entering correct one, this also did not work.
I get error - "Authorisation error - execution was rejected".
Is this because I have attempted 5 times with wrong password?
Appreciate any inputs!
