Using Wireshark, below is what I’m seeing for the two queries. The biggest
difference right off the bat is that the WO/EOModel search seems to search ROOT
as the base DN whereas the Apache DirectoryStudio is using
“DC=adinstance,DC=ucla,DC=edu” as the base. The WO/EOModel search also appears
to have additional objectClass ‘AND’ filters.
Looks like my first guess was somewhat likely - I need to find a way to get a
handle on the query and feed a base DN to my fetch in WO.
It looks like this might be a way to set that:
JNDIPlugin - base
<http://wocommunity.org/documents/javadoc/WebObjects/5.4.2/com/webobjects/jndiadaptor/JNDIPlugIn.html#base(com.webobjects.eocontrol.EOFetchSpecification, com.webobjects.eoaccess.EOEntity)>
But I’m wondering if there is a way to set it once at the launch of an app and
not have to set it again.
