[pmwiki-users] I want to auth based on pre-existing _SESSION variable with name in it.

I can make things work using $AuthUserFunctions and my own function.  But it 
requires a form submission.  Is there anyway to make this work if the _SESSION 
variable containing my id is merely present and somehow obtain correct PmWiki 
auth based on that?  Not interest in hearing about the security of this, I can 
take care of that later.  I just want to know if this can be done somehow.
