Condeco Missing User

Could not book in a user to a meeting room in Condeco.
It was discovered that the user did not exist in the Condeco system, so asked her to log in with her active directory credentials.
She logged on, and was then created as a user in Condeco.
However it was still not possible to make a booking under her name.
In active directory, the user did not have a firstname and lastname set. After setting the firstname and lastname (and waiting for replication) it became possible to book a meeting room for the user.

Condeco is searching active directory on the firstname and lastname fields, even although the user exists with this data in Condeco, it still searches active directory when trying to set a user to host a meeting.
