In http://samba.kn.vutbr.cz/samba/docs/Samba-HOWTO-Collection.pdf in section Domain Control, Domain Control Example Configuration, page 55 is smb.conf example with this: logon path = \{}\{}%N\{}profiles\{}%u It seems the \{} construct prevents the next character to be expanded to a special char by the \. There seems to be nothing about this in man smb.conf. I suggest adding this information in man smb.conf.
This is actually a bug in db2latex, which we use to generate the PDF. \{} is not supposed to do anything special. db2latex changes a normal '\' to '\{}'
originally reported against 3.0aph24. Bugzilla spring cleaning. Removing old alpha versions.
