Hi all, Has the subject says, I'm having problems with NTLM in *some* users, the logs show this when I request the page At first I tough this was related to a problem in some Windows 7 Laptops that don't have the reg key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa - DWORD LmCompatibilityLevel -> set to 1 to use LM NTLM and NTLMv2. The key was missing in the 2 laptops giving me the problem, but adding it and rebooting didn't solve the problem When the user opens IE/site (ntlm auth) I see this on cache.log: NTLMSSP challenge 2012/07/13 11:23:11.043| ConnStateData::swanSong: FD 33 Got 'YR TlRMTVNTUAADAAAAGAAYAJQAAAAYABgArAAAAAoACgBYAAAAGgAaAGIAAAAYABgAfAAAAAAAAADEAAAABYKIogYBsR0AAAAPHKcl6C2DGcPhZg1gFNMQqUMAQQBMAEUATQBDAGEAcgBsAGEAQwBhAHIAdgBhAGwAaABvAFcARABMAEgAUAA2ADMAMABOAEwAMAAyAJ3X1msrdlsCAAAAAAAAAAAAAAAAAAAAAL0k3O/g5/bRhTcU9HDH3PpqgbCc4abP4w==' from squid (length: 267). got NTLMSSP packet: got NTLMSSP command 3, expected 1 NTLMSSP NT_STATUS_INVALID_PARAMETER 2012/07/13 11:23:11.256| ConnStateData::swanSong: FD 33 This is when I send the "basic auth" Got 'YR TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAGAbEdAAAADw==' from squid (length: 59). got NTLMSSP packet: Got NTLMSSP neg_flags=0xa2088207 NTLMSSP_NEGOTIATE_UNICODE NTLMSSP_NEGOTIATE_OEM NTLMSSP_REQUEST_TARGET NTLMSSP_NEGOTIATE_NTLM NTLMSSP_NEGOTIATE_ALWAYS_SIGN NTLMSSP_NEGOTIATE_NTLM2 NTLMSSP_NEGOTIATE_VERSION NTLMSSP_NEGOTIATE_128 NTLMSSP_NEGOTIATE_56 NTLMSSP challenge 2012/07/13 11:23:33.226| ConnStateData::swanSong: FD 13 Got 'YR TlRMTVNTUAADAAAAGAAYAJQAAAAYABgArAAAAAoACgBYAAAAGgAaAGIAAAAYABgAfAAAAAAAAADEAAAABYKIogYBsR0AAAAP0dxfDL0xcw63QgT5XihRs0MAQQBMAEUATQBDAGEAcgBsAGEAQwBhAHIAdgBhAGwAaABvAFcARABMAEgAUAA2ADMAMABOAEwAMAAyAHncwjOdiQMNAAAAAAAAAAAAAAAAAAAAAGh+wPIBTsJQcYCTWvqvSQWmEPgrgyxOnw==' from squid (length: 267). got NTLMSSP packet: got NTLMSSP command 3, expected 1 NTLMSSP NT_STATUS_INVALID_PARAMETER 2012/07/13 11:23:39.436| ConnStateData::swanSong: FD 13 2012/07/13 11:23:40.451| ConnStateData::swanSong: FD 13 More info about my setup: squid -v Squid Cache: Version 3.1.19 configure options: '--sysconfdir=/usr/pkg/etc/squid' '--localstatedir=/var/squid' '--datarootdir=/usr/pkg/share/squid' '--enable-auth=basic,digest,ntlm' '--enable-cachemgr-hostname=localhost' '--enable-delay-pools' '--enable-icmp' '--enable-removal-policies=lru,heap' '--enable-poll' '--enable-storeio=ufs diskd' '--with-aio' '--disable-strict-error-checking' '--enable-icap-client' '--with-default-user=squid' '--with-pidfile=/var/run/squid.pid' '--enable-ipf-transparent' '--enable-carp' '--enable-snmp' '--enable-ssl' '--with-openssl=/usr' '--enable-basic-auth-helpers=getpwnam MSNT NCSA YP PAM' '--enable-digest-auth-helpers=password' '--enable-ntlm-auth-helpers=fakeauth' '--enable-external-acl-helpers=ip_user unix_group' '--prefix=/usr/pkg' '--build=x86_64--netbsd' '--host=x86_64--netbsd' '--mandir=/usr/pkg/man' 'build_alias=x86_64--netbsd' 'host_alias=x86_64--netbsd' 'CC=gcc' 'CFLAGS=-O2 -I/usr/include' 'LDFLAGS=-L/usr/lib -Wl,-R/usr/lib -Wl,-R/usr/pkg/lib' 'LIBS=' 'CPPFLAGS=-I/usr/include' 'CXX=c++' 'CXXFLAGS=-O2 -I/usr/include' --with-squid=/scratch/www/squid31/work/squid-3.1.19 --enable-ltdl-convenience Samba Version 3.6.5 OS: netbsd-6, samba and squid installed from pkgsrc Note: I do not have kerbuerus auth set up, because this is no easy task on netbsd, I still need to research on this.
