I was trying to login to Squirrelmail (hey I hear gripes its old, ugly, not web 2.0 – but it packs the punch of a 1972 Dodge Roadrunner – does only one or two well – very well).
Anyhow error message was: Error username or password incorrect
Error logs – Aborted login
Guess what – the issue was password aging – as I tried to login, I had to update my password. That fixed it instantly.
