vCAC 6: Lost one tenant

Hi,

Huge problem, I lost one of my tenant in vCAC 6.0. Other tenant with same identity stores works

A very nice error :

vCAC VA log :

vCAC ID log:

I tested my account to read AD account, everything is OK. Other tenant with my AD work well. But my tenant IT is down

The only difference with other tenant is that my tenant IT has 2 domain controller, one based on AD and one with Openldap.

Any help would be very appreciate
