Thanks for the reply. I understand what you are getting at. However, I do
have trouble compile the TNG code. And have for some time.

I would've tried the samedit program if I could get by the enumeration
constant problem on the first file make tries. Then if I comment out the
offending enumeration constant, I cannot get it to create the shared

I've sent several emails to this list (samba at regarding just
this problem and am a little offended that when AIX is having a problem it
seems to get ignored - similar to the email I sent regarding

I would love to use the TNG code for our installation, but simply can't
due to problems compiling and a lack of support.

As far as why we have to do things the way we are: simple - we're an
educational institution that must keep up to date with current hardware
and software technology. This means we have to roll out 3 builds a year -
one for each semester. Perhaps there are others in the same boat - or

Now, this is very simple for a staff of 3 to handle with the simple tool
known as smbpasswd. We're using 2.0.6 and don't have samedit.

If and when we can get the code to compile, we'll try it your way. Until
then we'll continue to find our own solutions.
