Hi,

it's been a while that I had problems with the PSP, but I ran into something recently :

Groups that have more than 1500 members generates an error when synchronizing them to our Active Directory. 

Test Group : acad:1801:Cours:A13_SPT6000-A

Number of members : 3059

Doing a manual calc on the groups returns the 3059 members that should be in the group.

Doing a manual diff on the group return 3059 ADD request, but in Active Directory, I see that the group already has more than 1500  members from an initial sync.

I believe the problem comes from an LDAP limitation of a maximum of 1500 retrieved members in a search. If there's more than 1500 members, the query need to have the "range=" option in it. The ldap used by the PSP isn't probably using it so it return no values. Since there's no values, the PSP tries to add the same members again and gets the below errors.

Since it's only 3 groups, it's not a big problem here, but it would be nice to have a fix for this problem.

Thank you
