Somehow I found this but still couldn't figure out solution to the below problems.
It states what could be wrong but how to fix that ??
Complete newbie with Outsystems and facing this issue
My login works in ServiceCenter but does not work in Users...
If you are having trouble logging in with a given username under Users, but are able to login just fine in ServiceCenter, your problem can be:
- an issue of multi-tenancy (somehow your user from Users got moved to a different tenant)
- your user in the Users provider is inactive
- your user in Users has a different password
- the entry for your Users object in the database has a different password, and you are not resetting it well
- Users is configured for external authentication [5] and the user does not exist in the external authentication system - so login is not possible.
In the opposite situation (you can login in Users but not in ServiceCenter) you were probably never created as an IT user. In that situation, request that a user is created for you under ServiceCenter / LifeTime.
