Working with Active Directory on Windows Server 2012 R2

I?ve attempted the user Mail with the same password with the same result
(binding as my own user was a last-ditch attempt).

aaron at aaron-Parallels-Virtual-Platform:/etc/sssd$ ldapsearch -x -H
ldap://dc1.ad.automaton.uk -D 
CN=aaron.jenkins,CN=users,DC=ad,DC=automaton,DC=uk -W - -b
CN=aaron.jenkins,CN=users,DC=ad,DC=automaton,DC=uk
Enter LDAP Password:
# extended LDIF
#
# LDAPv3
# base <CN=aaron.jenkins,CN=users,DC=ad,DC=automaton,DC=uk> with scope
subtree
# filter: (objectclass=*)
# requesting: -
#

# aaron.jenkins, Users, ad.automaton.uk
dn: CN=aaron.jenkins,CN=Users,DC=ad,DC=automaton,DC=uk

# search result

Same with the user Mail

Your conf:
auth_bind = yes
dn = aaron.jenkins
dnpass = dummypass1
auth_bind_userdn = CN=%u,CN=users,DC=ad,DC=automaton,DC=uk

Can you really succeed a simple auth with the dn aaron.jenkins ? This
ought to be a full DN. As I understand auth_bind_userdn, you do not need
dn/dnpass anyway, because auth_bind_userdn prevents searching for the
user's DN, in which case Dovecot requires a connection before any user
bind takes place.

I wonder if the log shows the error from this setting or from the user's
login attempt. Could you try another user?

Can you auth from command line via

ldapsearch -x -H ldap://dc1.ad.automaton.uk -D \
CN=aaron.jenkins,CN=users,DC=ad,DC=automaton,DC=uk -W \
- -b CN=aaron.jenkins,CN=users,DC=ad,DC=automaton,DC=uk

Did you removed the dn/dnpass settings?

What about the:> I wonder if the log shows the error from this setting or from the

If you login with another user (not aaron.jenkins) to IMAP, which
username is listed in the logs then.
