[pmwiki-users] Recipe for making logging succesful logins?

[f.r.salomons]

I am trying to make a pmwiki-website intended for use by a restricted 
group only. Most pages are therefore restricted for viewing and editing. 
Is there a way to log succesful logins by members of the user group? 
Preferably without also logging visits to the homepage (which is open to 
anybody). Is there a way to configure one of the logging recipes so as 
to achieve this?
