Just write it  :-

BeginGroupIfNoLineMatching "^ *;* *logon path = [\][\]%N[\]USERPROFILES[\]%U( 
+(;.*)?)?$"

    >> - there could be several spaces around the =

    Juri> There isn't...

In your case perhaps, I just meant in general smb.conf can have
multiple spaces and it is normally better to be flexible to begin
with.

    Juri>    logon path = \\%N\USERPROFILES\%U ; Edited by cfengine

Oh, as in the one you are replacing it with :-)

Right, I've been testing this with perl and having lots of fun. Yes,
it is the backslashes. Using [\] gives problems because \] is just an
escaped ] possibly. I've tried various variations and I'm currently
stumped although you could try [\\] to see if that helps.

Stop the press !! I got it working using :-

^ *;* *logon path = [\\][\\]%N[\\]USERPROFILES[\\]%U( +(;.*)?)?$

Try that and let me know if it works as it works using perl at least
but I haven't checked with cfengine

Sincerely,

Adrian
