| 31 | <para><command>ntlm_auth</command> is a helper utility that authenticates
|
|---|
| 32 | users using NT/LM authentication. It returns 0 if the users is authenticated
|
|---|
| 33 | successfully and 1 if access was denied. ntlm_auth uses winbind to access
|
|---|
| 34 | the user and authentication data for a domain. This utility
|
|---|
| 35 | is only indended to be used by other programs (currently squid).
