Maybe a solution to samba problems.

[Fintan]

I just got this bug report solution:
https://bugs.launchpad.net/bugs/95452

with this solution:

Using Kubuntu Gutsy
Work around by commenting 2 lines works
##########Evil############
#case sensitive = no
#msdfs proxy = no

Another work around is to make sure that the section "Misc" in smb.conf has the folling option:
############ Misc ############
...
host msdfs = no

The above option can be set from the Kcontrol module and is by default "host msdfs = yes"
Kcontrol-> Internet -> Samba -> Advanced -> VFS -> Host msdfs checkbox.
I could not find the option in the standard System settings.

If this option is set it is not necessary to comment the lines "msdfs
proxy" and "case sensitive = no"

I hope this helps a few people here
