Another way to fix pdbedit segfaults in Samba 3.0

[Jianliang Lu]

As we know, the pdbedit from samba3.0 alpha21 got segfaults when you don't
give the user_name. There is a fix about this on the CVS, but I think that 
the fix does not do that the pdbedit should do, that means, if you don't 
give the user_name the tool should show all users, but not exit like the fix 
did.
I've fixed the problem in another way, that if you run pdbedit without a 
user_name it show all users, otherway, it show the user that you sepcified.
I have tested it and it worked!

The patch is following: (the pdbedit.c.rel is that from samba team)

    if (!lp_load(dyn_CONFIGFILE,True,False,False)) {
        fprintf(stderr, "Can't load %s - run testparm to debug it\n",
