I have installed iFolder 2.1 on a NW6 SBS SP2 server and all worked
fine. I then installed
SP3 and now the iFolder users are being told that they are not
authorized. I have tried
going back to SP2 but this just gave me LDAP problems.

At the moment I have SP3 on and all the users have been told that they
are not authorized.
I have done an LDAP trace and have got the following error.

DDCReadStream failed in WGetLDAPStreamValue, err = -649
Searching "": NDS error:-649 returned.
LDAPSearchToCB failed, err = -649

I can find nothing on this error code.

Ldap seems to be working fine as I can login as admin on the iFolder
admin web console.

PLEASE HELP.
