We restored to 3.0.23d after update to 3.0.25a because of strange dfs behavior.

the detailed situation:

on msdfs root server 'samba' ls -lR

drwxr-xr-x appl1

lrwxrwxrwx share1 -> msdfs:server1\share1

        comment = "SaMBa DFS root"
        path = /path.../dfsroot
#       next line does not work prior 3.0.25 !!!
#       hide unreadable = Yes
        msdfs root = Yes

on 'server1' ls -lR

drwxrws---  folder1
drwxrws---  folder2

        path = /path.../share1
        valid users = +opr
        force group = opr
        printable = no
        writeable = yes
        inherit permissions = Yes

The failing clients are Windows Server 2003 SP1 with Citrix MetaFrame Presentation Server 4.0
rebooted after update to 3.0.25a.

The first view (windows explorer) after the update is ok


But after a while (maybe other citrix users mapping \\samba\dfs in the meantime ...)

the view from the same connection looked like


causing applications to fail

Standard WinXP clients had the same strange folder duplication, but seemed to behave ok after remapping and reboot.

The Problem looks simular like the one reported by Josh Kelley (Jun 4) 'msdfs root problems even after a reboot?'

Any help appreciated
