[Grok-dev] login event and subscribe to

[Jens Adner]

After changing the code to "IAuthenticatedPrincipalCreated", no results.
This event is initiating every view too.

I want write some infos to a mysql database as result of auth event:

 uid = principal.id.split('.')[-1]
 utils.logme("myapp","login",uid,"ip address")

Currently, every browser request writes the data.

Best regards
Jens
