LDAP authentication | limit to groups inside AD

Hello everyone,

 

I have alfresco community 6.2 with docker already working with Active Directory authentication.

But I'm facing the issue that everybody inside the AD is able to login to Alfresco also like service accounts which is not the best situatin. I thought I had reduced it to LDAP path inside the AD for configured alfresco OU which I created for this. In this OU there is only two groups configured where are the users which need to login to alfresco. But this did not work.

My goal is to allow only users which are inside the alfresco group inside the AD, is there any possibility to bring this to work?

Here is my config:

alfresco.authentication.allowGuestLogin=false
ntlm.authentication.mapUnknownUserToGuest=false
create.missing.people=false

### LDAP authentication ###

ldap.synchronization.groupDisplayNameAttributeName=displayName
ldap.synchronization.groupType=group
ldap.synchronization.personType=user
ldap.synchronization.groupMemberAttributeName=member
ldap.synchronization.enableProgressEstimation=true

I also tried  a change on the person and group query with:

ldap.synchronization.personQuery=(&(objectclass\=user)(userAccountControl\:1.2.840.113556.1.4.803\:\=512)(|(memberOf=cn\=alfresco-admin,ou=alfresco,ou=USEDOU,ou=USEDOU,dc=domain,dc=tld)(memberOf=cn\=alfresco-user,ou=USEDOU,ou=USEDOU,ou=USEDOU,dc=domain,dc=tld)))

ldap.synchronization.personDifferentialQuery=(&(objectclass\=user)(userAccountControl\:1.2.840.113556.1.4.803\:\=512)(|(memberOf=cn\=alfresco-admin,ou=alfresco,ou=USEDOU,ou=USEDOU,dc=domain,dc=tld)(memberOf=cn\=alfresco-user,ou=USEDOU,ou=USEDOU,ou=USEDOU,dc=domain,dc=tld))(!(modifyTimestamp<\={0})))

Also the same.

I already tried to add the following:

create.missing.people=false
synchronization.autoCreatePeopleOnLogin=false
synchronization.syncWhenMissingPeopleLogIn=false

But with this config, no new user is able to login, because the user will not be created inside alfresco - so also not a real soloution to provide new users access to alfresco.

 

So is there any chance to get ldap authentication for users inside a group get to work without allowing anybody to login?

 

Many thanks in advance for your help.

 

Best regards
