Problem updating user info from LDAP

Hi, all!

I have RT 3.4.5 installed with LDAP Authentication support. The system
is configured to update user info on local RT database upon user login,
using data from LDAP. At this moment, this authentication is working and
all fields are correctly updated, except by ‘Organization’.

I’ve already mapped my ‘ou’ LDAP attribute to ‘Organization’ in, however it’s not working. But, if I map ‘ou’ to
another user field (‘City’, for example), then it works fine. I can’t
figure out what is wrong, it seems that RT refuses to update this field.

Through the web admin interface, modifications on Organization also work.

If someone have any hint, please tell me.
