It returns 0 if the users is authenticated successfully and 1 if access was denied\&. ntlm_auth uses winbind to access the user and authentication data for a domain\&. This utility is only intended to be used by other programs (currently +Squid +and +mod_ntlm_winbind) +.SH "OPERATIONAL REQUIREMENTS" +.PP +The +\fBwinbindd\fR(8) +daemon must be operational for many of these commands to function\&. +.PP +Some of these commands also require access to the directory +winbindd_privileged +in +$LOCKDIR\&. This should be done either by running this command as root or providing group access to the +winbindd_privileged +directory\&. For security reasons, this directory should not be world\-accessable\&. +.SH "OPTIONS" +.PP +\-\-helper\-protocol=PROTO +.RS 4 +Operate as a stdio\-based helper\&. Valid helper protocols are: +.PP +squid\-2\&.4\-basic +.RS 4 +Server\-side helper for use with Squid 2\&.4\*(Aqs basic (plaintext) authentication\&. +.RE +.PP +squid\-2\&.5\-basic +.RS 4 +Server\-side helper for use with Squid 2\&.5\*(Aqs basic (plaintext) authentication\&. +.RE +.PP +squid\-2\&.5\-ntlmssp +.RS 4 +Server\-side helper for use with Squid 2\&.5\*(Aqs NTLMSSP authentication\&. +.sp +Requires access to the directory +winbindd_privileged +in +$LOCKDIR\&. The protocol used is described here: +http://devel\&.squid\-cache\&.org/ntlm/squid_helper_protocol\&.html\&. This protocol has been extended to allow the NTLMSSP Negotiate packet to be included as an argument to the +YR +command\&. (Thus avoiding loss of information in the protocol exchange)\&. +.RE +.PP +ntlmssp\-client\-1 +.RS 4 +Client\-side helper for use with arbitrary external programs that may wish to use Samba\*(Aqs NTLMSSP authentication knowledge\&. +.sp +This helper is a client, and as such may be run by any user\&. The protocol used is effectively the reverse of the previous protocol\&. A +YR +command (without any arguments) starts the authentication exchange\&. +.RE +.PP +gss\-spnego +.RS 4 +Server\-side helper that implements GSS\-SPNEGO\&. This uses a protocol that is almost the same as +squid\-2\&.5\-ntlmssp, but has some subtle differences that are undocumented outside the source at this stage\&. +.sp +Requires access to the directory +winbindd_privileged +in +$LOCKDIR\&. +.RE +.PP +gss\-spnego\-client +.RS 4 +Client\-side helper that implements GSS\-SPNEGO\&.

The presence of a single period +\&. +indicates that one side has finished supplying data to the other\&.
