My Turba Backend consists of an LDAP directory where a vast majority  
of users have their DisplayName (and givenName/sn) stored with accents  
and special chars (like "ñ, ó, á, etc.." ).

So, when i try to add them to an event trought kronolith, it raises an  
error saying : "Validation Failed for: xxxxxxx <xxxxx at domain.xxx>", if  
i add an user from that directory whose DisplayName doesn't contain  
special chars, the error is not raised and the calFBURL address from  
LDAP is checked properly, even bringing up their availability correctly.

Validation doesn't fail also when instead of using the user name (if  
it contains special chars) i add the atendee directly by email  
address, but of course, autocomplete is there for a reason.

Is there any way to make kronolith ignore the formal name of the  
atendee and just checks the mail address?
