%globalentities; ]> ntlm_auth 1 ntlm_auth tool to allow external access to Winbind's NTLM authentication function ntlm_auth -d debuglevel -l logfile -s <smb config file> DESCRIPTION This tool is part of the Samba 7 suite. ntlm_auth is a helper utility that authenticates users using NT/LM authentication. 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 indended to be used by other programs (currently squid). OPERATIONAL REQUIREMENTS The winbindd 8 daemon must be operational for many of these commands to function. 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. OPTIONS --helper-protocol=PROTO Operate as a stdio-based helper. Valid helper protocols are: squid-2.4-basic Server-side helper for use with Squid 2.4's basic (plaintext) authentication. squid-2.5-basic Server-side helper for use with Squid 2.5's basic (plaintext) authentication. squid-2.5-ntlmssp Server-side helper for use with Squid 2.5's NTLMSSP authentication. 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 gss-spengo Server-side helper that implements GSS-SPNEGO. This also uses the same as squid-2.5-ntlmssp and is described here: http://devel.squid-cache.org/ntlm/squid_helper_protocol.html gss-spengo-client Client-side helper that implements GSS-SPNEGO. This also uses a protocol similar to the above helpers, but is currently undocumented. --username=USERNAME Specify username of user to authenticate --domain=DOMAIN Specify domain of user to authenticate --workstation=WORKSTATION Specify the workstation the user authenticated from --challenge=STRING NTLM challenge (in HEXADECIMAL) --lm-response=RESPONSE LM Response to the challenge (in HEXADECIMAL) --nt-response=RESPONSE NT or NTLMv2 Response to the challenge (in HEXADECIMAL) --password=PASSWORD User's plaintext passwordIf not specified on the command line, this is prompted for when required. --request-lm-key Retreive LM session key --request-nt-key Request NT key --diagnostics Perform Diagnostics on the authentication chain. Uses the password from --password or prompts for one. &popt.common.samba; &stdarg.help; EXAMPLE SETUP To setup ntlm_auth for use by squid 2.5, with both basic and NTLMSSP authentication, the following should be placed in the squid.conf file. auth_param ntlm program ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param basic program ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours This example assumes that ntlm_auth has been installed into your path, and that the group permissions on winbindd_privileged are as described above. VERSION This man page is correct for version 3.0 of the Samba suite. AUTHOR The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed. The ntlm_auth manpage was written by Jelmer Vernooij and Andrew Bartlett.
