I missed that, but when I’m enabling it I get the following exception :

 

Caused by: java.lang.ClassNotFoundException: edu.internet2.middleware.ldappc.util.RangeSearchResultHandler

 

Is it in a different package ? did the package name change over time ?

 

Also it seems the example line included is outdated since I’ll get a different error if I try it (java.lang.ClassNotFoundException: edu.internet2.middleware.ldappc.util.QuotedDnResultHandler). I tried adding the RangeSearchHandler in the current line, but then I get the above error.

Hi Sebastien,

 

Have you enabled the RangeSearchResultHandler in your ldap.properties?

 

# handle Active Directory groups with a large (>1500) number of members

# see https://bugs.internet2.edu/jira/browse/GRP-335

# see http://code.google.com/p/vt-middleware/wiki/vtldapAD#Range_Attributes

 edu.vt.middleware.ldap.searchResultHandlers=edu.internet2.middleware.ldappc.util.QuotedDnResultHandler,edu.vt.middleware.ldap.handler.FqdnSearchResultHandler,edu.internet2.middleware.ldappc.util.RangeSearchResultHandler

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
