Error recovery – recover lost users.

In the event of loosing some users from the database for any unknown reason (deleting a file manually etc) you can rebuild the user database like this using the journal entries it keeps.

# First copy nwauth.* files

mkdir backup

copy nwauth.* backup

# Then use this command to get a list of changes it will make:

nwauth -path . -test

# Then run it with -fix to actually add the missing users:

nwauth -path . -fix

Supported Commands

The commands below are the list of commands that this module supports.

check<user> <pass>
set<user> <pass>|(NULL) [label=”value”]
search<string> [-from n] [-max m]

To make passwords visible in admin

Obviously this is not recommended as it is a security risk, but on a small or home server this may be worth doing:

Use these two settings

g_authent_process “c:\surgemail\nwauth.exe -path c:\surgemail -nocrypt -decrypt -showpass”

g_authent_info name=”Password” field=”password” access=”admin” default=”” type=””
