/* This was set by JHT in liaison with Jeremy Allison early 1997
* History:
* Version 4.0 - never made public
* Version 4.10 - New to 1.9.16p2, lost in space 1.9.16p3 to 1.9.16p9
* - Reappeared in 1.9.16p11 with fixed smbd services
* Version 4.20 - To indicate that nmbd and browsing now works better
* Version 4.50 - Set at release of samba-2.2.0 by JHT
*
* Note: In the presence of NT4.X do not set above 4.9
* Setting this above 4.9 can have undesired side-effects.
* This may change again in Samba-3.0 after further testing. JHT

"NEVER_MAP_TO_GUEST" means session setups with an invalid password
are rejected. This is the default.
"MAP_TO_GUEST_ON_BAD_USER" means session setups with an invalid password
are rejected, unless the username does not exist, in which case it
is treated as a guest login
"MAP_TO_GUEST_ON_BAD_PASSWORD" means session setups with an invalid password
are treated as a guest login
Note that map_to_guest only has an effect in user or server
