I spent some tedious time writing a preexec and a script for capturing all
those variables which samba has when a user logs in. I thought I would pass
them along, just in case someone else finds them useful.
The smb.conf preexec isn't very pretty. I can't be sure it will work in
its
present form, since in my smb.conf file it was all one long line, but when I
cut and pasted it into this email vi automatically put in returns. I put in
\ at the end of each line so things might work just fine as it is.
The preexec close = yes makes samba deny the connection if the preexec
script returns an error code. Very handy. I call this a preexec script, but
SWAT calls them exec scripts and removes the pre, but it is the same thing.
Maybe SWAT removes those carriage returns, too. Not sure.

comment = Root directory
path = /
read only = No
create mask = 0766
guest ok = Yes
preexec close = yes
exec = rm /tmp/Hello;echo \"m %m \" \"G %G \"
\"I %I \" \"L %L \" \
\"M %M \" \"N %N \" \"R %R \" \"T %T \"
\"U %U \" \
\"a %a \" \"d %d \" \"h %h \" \"p %p \"
\"v %v \" \
\"H %H \" \"P %P \" \"S %S \" \"g %g \"
\"u %u \" | xargs -n1 /usr/local/samba/bin/Hello;
To make things confusing, I called the data file Hello and the script
Hello, but, since they are in different directories, that shouldn't be a
problem.

This is the script Hello:
#!/bin/bash
i=`echo "$1" | tr -s " "`
index=`echo "$i" | cut -d" " -f1`
value=`echo "$i" | sed 's/^. //'`
