SonarQube LDAP Authentication seems to load but won't allow login via domain user

Question

I've been trying to setup SonarQube (v4.1) with the LDAP authentication plugin (v1.4) and I just can't get it to authenticate against my domain user. My config is setup as follows:

#########################
# LDAP configuration
#########################
# General Configuration
sonar.security.realm=LDAP
sonar.security.savePassword=true
sonar.security.updateUserAttributes=true
sonar.authenticator.downcase=true
sonar.authenticator.createUsers=true

ldap.authentication=simple
ldap.realm=mydomain.co.uk
ldap.bindDn=CN=USERNAME,OU=developers,DC=mydomain,DC=co,DC=uk
ldap.bindPassword=PASSWORD

# User Configuration
#ldap.user.baseDn=OU=developers,DC=mydomain,DC=co,DC=uk
ldap.user.request=(&(objectClass=user)(sAMAccountName={login}))
ldap.user.realNameAttribute=cn
ldap.user.emailAttribute=mail

# Group Configuration
ldap.group.baseDn=CN=Domain Users,CN=Users,DC=adastra,DC=co,DC=uk
ldap.group.request=(&(objectClass=group)(member={dn}))

and the log outputs the following messges that seem to say that the LDAP connection is working fine:

2014.01.20 16:12:32 INFO  [org.sonar.INFO]  Security realm: LDAP
2014.01.20 16:12:32 INFO  [o.s.p.l.LdapSettingsManager]  Auto discovery mode
2014.01.20 16:12:32 INFO  [o.s.p.l.LdapSettingsManager]  Detected server: ldap://dc02.mydomain.co.uk:389

2014.01.20 16:12:32 INFO  [o.s.p.l.LdapSettingsManager]  Group mapping: LdapGroupMapping{baseDn=CN=Domain Users,CN=Users,DC=mydomain,DC=co,DC=uk, idAttribute=cn, requiredUserAttributes=[dn], request=(&(objectClass=group)(member={0}))}
2014.01.20 16:12:32 INFO  [o.s.p.l.LdapContextFactory]  Test LDAP connection on ldap://dc02.mydomain.co.uk:389: OK
2014.01.20 16:12:32 INFO  [org.sonar.INFO]  Security realm started

But it just doesn't seem to work for my user unless I use a local user. When enabling logging on the wrapper by setting:

wrapper.console.loglevel=DEBUG

I get the following error in the logs which doesn't really help that much! :)

2014.01.20 17:07:10 ERROR [rails]  Error from external users provider:

Using port 3268 did the trick for me. Here is my configuration that works with SonarQube 5.0.1 and Active Directory:

sonar.security.realm=LDAP
sonar.security.savePassword=true
sonar.security.updateUserAttributes=true
sonar.authenticator.createUsers=true

ldap.url=ldap://dc101.office.company.com:3268
ldap.bindDn=CN=Service Account,OU=Windows Service,OU=Accounts,OU=Resources,DC=office,DC=company,DC=com
ldap.bindPassword=PASSWORD

ldap.user.baseDn=DC=office,DC=company,DC=com
ldap.user.request=(&(objectClass=user)(sAMAccountName={login}))
ldap.user.realNameAttribute=cn
ldap.user.emailAttribute=mail
