This document is meant to describe some known causes and solutions for slow login / login hang of Database user connection. This doesn't apply for multiple different ordinary users concurrently logging in to separate accounts.

This document describes an issue which would ONLY occur when multiple concurrent logons using the correct password are performed to the same account concurrently while at the same time some concurrent logon attempts are made with the wrong password, causing the "Failed Login Delay" code to acquire an exclusive lock to enforce the failed login delay (one second usually).
