Hi Oleg and Shimi.
I did not describe problem correctly.
This is not Linux sysadm problem.
I am fixing application running on Debian,
I will take Oleg's advice to see cntlm source.
Today I was surprised by ldapsearch utility ( package ldap-utils) which
reports that are several authentication mechanism available on AD server,
like GSS-API, KERBEROS, OTP
but it did not listed NTLM !!!
on the other hand I see that ad browser from sysinternals suite for
windows do use NTLM ( wireshark sees it)
So I am confused now :
Can linux use NTLM as some backdoor method, or only windows can use it?
Perhaps NTLM plugin of openldap library is usable only on LDAP server to
authenticate windows clients?

Hello Alll,
Does anybody have example or can advice how to perform NTLM
authentication of Linux client toward Microsoft AD service?
I calledd ldap_ntlm_bind() to do the Job, but
Wireshark can not fully recognize these message and prints
"mailformed"
And following
ldap_parse_ntlm_bind_result() returns with Authentication error.
Unfortunately these functions are not documented, perhaps I pass
wrong parameters.
Actually I pass
ldap_ntlm_bind(ld, dn, LDAP_AUTH_NTLM_REQUEST, cred, NULL, NULL,
msgidp);
I put password in cred structure and user parameter as part of dn
string,
like "user=NTDOMAIN\lev, cn=myhost,dn=com"
Many thanks and Hag Sameah,
Tried already the 'regular' way
(https://help.ubuntu.com/community/ActiveDirectoryWinbindHowto) and
saw if that works? Maybe the issue is not with your code...
Not that I am sure what are you trying to do beyond just
authenticating (if it's just login or similar, why really not with
winbind through PAM?) - maybe I got it all wrong :-)
IIRC, to use LDAP towards an AD server, it must be a GlobalCatalog -
you should make sure that is the case (as well as the right port for
the job, whether encryption is used or not, etc etc.). But this is
ancient history, so I hope I am not misleading you.
