the problem we have seen is related with WC install with PDMLink.
we were facing issue when LDAP password we provided contains characters which was not acceptable by ldap later on.
I have generated password through password generator and put this into PSI and not received any error message. during WC Ds installation it was throwing an error and only after working with support, spending hours we understood that this is due to characters in password.
it will be very valuable if PSI actually validates all the inputs.
