Problem with user access rights - by: Poelstra

Hi,

I've some problems giving a user the correct access rights. Any help would be appreciated.
I've the following project structure (showing also the profile of the user for the project)
Project 1 (Project Member)
-Project 2 (Project Member)
--Project 3 (Project Leader)

In the 'Planning' form when he selects any project he gets the following message:
You don't have rights to access this Project.

Any subactivities that he selects are shown fine (even from projects he is not allocated to), although he is not able to create any new activities.

The 'Access to data (project dependant)' form show that a 'Project leader' is a 'Manager' for both 'Projects' and 'Activities'.

How can I find out why access is denied? And what should I change to make sure that this user has access to Project 3?

Thanks in advance.

Kind regards,

Remco Poelstra
