Attached is a debdiff to revert the changes we made to adcli to restore functionality to GSS-API.
** Patch added: "Debdiff for adcli on Bionic" https://bugs.launchpad.net/ubuntu/+source/adcli/+bug/1906627/+attachment/5441133/+files/lp1906627_adcli_bionic.debdiff -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cyrus-sasl2 in Ubuntu. https://bugs.launchpad.net/bugs/1906627 Title: adcli fails, can't contact LDAP server Status in adcli package in Ubuntu: Fix Released Status in cyrus-sasl2 package in Ubuntu: New Status in adcli source package in Bionic: In Progress Status in cyrus-sasl2 source package in Bionic: New Bug description: Package: adcli Version: 0.8.2-1ubuntu1 Release: Ubuntu 18.04 LTS When trying to join the domain with this new version of adcli, it gets to the point of 'Using GSS-SPNEGO for SASL bind' and then it will not do anything for 10 minutes. It will then fail, complaining it can't reach the LDAP server.

Failed to join the domain Dec 03 01:55:27 example001.domain.com realmd[6419]: ! Failed to join the domain On the network level, adcli gets to the point of send an ldap query to the domain controller and the domain controller returns an ack tcp packet, but then there is no more traffic between the domain controller and the server except for ntp packets until it fails. The domain controller traffic also shows that it is receiving the ldap query packet from the server but it never sends a reply and there is no log in directory services regarding the query. We also couldn't find anything in procmon regarding this query either. Workaround/Fix: Downgrading the adcli package back to version 0.8.2-1 fixes the issues and domain join works properly again.
