Hi

I am trying to find out who is logging into sugar and when. I have five users in the users table each with an ID.
In the tracker table, there is a user_id column that I can tie into the tracker table and there is a module name column with some entries that contain 'Users'

The following is part of the data from the tracker table.
362 41022e0c-fde1-038f-30da-4980af855dda NULL Users
365 67a2bbea-d2dc-e495-7e00-4980afa5d345 6e7bccff-f33f-f115-4e58-49518708711f Users
362 shows NULL in the user_id column where as 365 actually has a user_id

Does anyone know where NULL can be coming from since I do not see a record in the User table with an ID of NULL?
