Virtual List View Active Directory search using Novell.Directory throws LdapException: Unavailable Critical Extension

Question

Same paging code works against a test domain controller, but doesn't work against another different AD domain that has same similar setup (Windows 2012 r2 based). DisableVLVSupport=0 on both domains.

LdapException: (12) Unavailable Critical Extension
LdapException: Server Message: 000020EF: SvcErr: DSID-03140552, problem 5010 (UNAVAIL_EXTENSION), data 0

Error code: 53

Answer 1

I was able to reproduce the issue on the working domain by setting MaxTempTableSize to a value smaller than the total count of users in cn=Users dn. It turns out that MaxTempTableSize should be bigger than the total count of the paged result. One of the main differences between the two Active Directory domains was mainly that the second one had a huge number of users.

Used Ntdsutil.exe tool to set the LDAP Policy property value.
