Problems with Slide Client and SAP Portal WebDAV

I'm having the most peculiar behavior when using the Slide cmdline
client against the SAP Portal WebDAV service.  It connects ok.  However,
running ls commands doesn't show the contents correctly - leaves out
folders.  When I turn on debug, I can see the "lost"
collections/resources in the XML output.   I can connect using the same
credentials using Win2k Network Place connection and navigate folders
just fine.
 
ls and ls -l also return different results.  I tend to see less
resources with ls -l.
 
Since I can browse the WebDAV service via Windows Explorer, I know what
folders should be there.  I can cd to specific paths that I know via
Windows Explorer.  However, running forms of ls continue to return
incorrect results.
 
Only a few of the folders in question return HTTP 403, which seems to
mean that I don't have permission to those folders - which is expected.
Sometimes the 403 folders are displayed in results of ls -l, but not ls.
This seems very weird and wrong.
 
It's been a few months and lots of other projects, but I'm certain that
I've successfully used Slide to connect and browse a SAP Portal WebDAV
service.   The alleged success was a different SAP Portal WebDAV
service.
