A big Directory Access mistake

[Steve St-Laurent]

Not sure exactly what I did but adjusting a couple of settings in 
Directory Access and running Open Directory Assistant I managed to 
wreck access. No passwords accepted at login. Used the installer disk 
to reset the root password, which lets me reboot, only dumped into 
single-user mode. Running forensics on stupidity is iffy at the best of 
times, but does anyone have any ideas on what happened?

The whole thing left me too frazzled to remember what I changed, A 
couple of questions arising from this:

1. On a stand-alone server what are typical settings for Directory 
Access and Open Directory?

2. Being only half-stunned, I used a barebones 10.2 Server installed on 
a separate partition to restore services. Are there particular 
directory-access settings or preferences that could be trashed on the 
original server -- to be rebuilt or copied from second server -- which 
would restore the first server?

3. Is this an instance of Authorization Trampoline? [Found an item by 
this name in Core Services and just dying to know what the heck it is.  
:~]
