only allow synced users to authenticate

[astacey]

Hello All,

Is it possible to only allow synchronized users to login to the share web gui? If so what strings need to be added to the global properties?

Many thanks in advance for any replies.

Which users do you not want to be able to login?

[mrogers]

No.

So how do i define which users can login to alfresco? i do not want every user in my AD to be able to login. I now have an ldap authentication subsystem working and alfresco is only synchronizing users in a certain AD security group. but i only want users in this security group to authenticate to the share web gui.

you need to change your ldap query to only select those users you want to be able to log in.    There will be examples in these forums where someone restricts alfresco to members of another ldap group.

Hi mrogers,

I have been all over the internet trying to find what this query is. do you have an example?

Here is what i am using so far:

### LDAP authentication chain
authentication.chain=ldap1:ldap-ad
ntlm.authentication.sso.enabled=true

### LDAP Authentication
ldap.authentication.active=true
ldap.authentication.allowGuestLogin=false
ldap.authentication.userNameFormat=%s@domain.co.uk
ldap.authentication.java.naming.provider.url=ldap://dc01.domain.co.uk:389
ldap.authentication.defaultAdministratorUserNames=adminuser1,adminuser2,adminuser3

### LDAP Synchronization
ldap.synchronization.java.naming.security.principal=alfrescohttp@domain.co.uk
ldap.synchronization.java.naming.security.credentials=ssssshhhhh
ldap.synchronization.active=true
ldap.synchronization.groupQuery=(objectclass\=group)
ldap.synchronization.groupSearchBase=ou=Int,ou=Manage,dc=domain,dc=co,dc=uk
ldap.synchronization.groupDifferentialQuery=(&(objectclass\=group)(!(modifyTimestamp<\={0})))
ldap.synchronization.personType=user
ldap.synchronization.personQuery=(&(|(memberof=CN=alfresco.users,OU=Int,OU=Manage,DC=domain,DC=co,DC=uk)(objectclass\=user)(userAccountControl\:1.2.840.113556.1.4.803\:\=512))
ldap.synchronization.personDifferentialQuery=(&(objectclass\=organizationalPerson)(!(userAccountControl\:1.2.840.113556.1.4.803\:\=2))(!(modifyTimestamp<\={0})))
ldap.synchronization.userSearchBase=ou=Admin Accounts,ou=company,dc=domain,dc=co,dc=uk


I am also getting this issue in the alfresco.log:

Do you have any idea why this is failing to resolve the user when it is finding the information? As these users are in a different OU to my searchbase, could this be causing the issue? do i need to add this OU to my searchbase as well?

[astacey]

I am getting closer with this but i am now getting this warn message when trying to syncronize a security group in AD

11:13:03,785 WARN  [org.alfresco.repo.security.sync.ldap.LDAPUserRegistry] [localhost-startStop-1] Missing GID on {member;range=0-*=member;range=0-*: CN=adminuser1,OU=Admin,OU=Users,DC=domain,DC=co,DC=uk, CN=adminuser2,OU=Admin,OU=Users,DC=domain,DC=co,DC=uk, whenchanged=whenChanged: 20141112145257.0Z}


Does anyone know why this is missing the gid?

[catar4]

"GID" stands for Group ID. Did you also adjust your "groupSelection" query ? I would guess the synchronization needs to sync groups as well as users. That or the users it's trying to sync are not in any groups (and they'd need to be) ? Just a quick guess.

[astacey]

Hi all,

so it seems that it is possible to allow only syncronized users to be able to login:

synchronization.syncOnStartup=true
synchronization.autoCreatePeopleOnLogin=false
synchronization.syncWhenMissingPeopleLogIn=false


Just need to add this to the gloabl properties.

It concerns me that that senior software engineers do not know this. but i spose they are like this software.
