We have a considerable regression suite for testing normal and not so normal gssapi functions as part of exercising omi and powershell. We have been running that quite often, as passing it is required for checkin. In addition we have been using it a fair amount in more informal testing.
I built a custom gss-ntlmssp-0.7.0 deb for trusty from the sources from the page on fedorahosted and the package info for the xenial .deb. The setup on trusty is a little weird (/usr/etc/gss/mech rather than /etc/gss/mech.d/ntlmssp.conf for example) but it has represented no problems with that modification. With the packages, everything works a treat. Without we are unable to encrypt traffic using NTLMv2 and have it understood by windows. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to krb5 in Ubuntu. https://bugs.launchpad.net/bugs/1643708 Title: Add SPNEGO special case for NTLMSSP+MechListMIC Status in krb5 package in Ubuntu: Fix Released Status in krb5 source package in Trusty: Fix Committed Status in krb5 source package in Xenial: Fix Committed Status in krb5 source package in Yakkety: Fix Committed Bug description: [Impact] MS-SPNG section 3.3.5.1 documents an odd behavior the SPNEGO layer needs to implement specifically for the NTLMSSP mechanism.
