How to know is Alfresco user logged in by LDAP or not?

[alexsolomatin]

Hi.

I need to get the details about user logging in. I have Alfresco NTLM authentication and LDAP authentication in my authenticatiion chain. I enabled LDAP synchronization too. How can I know in what way the user was logged in the system? Now I'm getting the all data from the properties file for LDAP authentication. And I'm trying to get the person object by PersonService and investigate whether it has the parent with the name  /{http://www.alfresco.org/model/system/1.0}system/{http://www.alfresco.org/model/system/1.0}zones/{htt... or not. But I can't check it. It seems I haven't got permissions for the System user for doing it. I got the exception:

16:08:17,228 ERROR [com.smartech.alfresco.module.iconnector.AlfrescoLdapController] net.sf.acegisecurity.providers.ProviderNotFoundException: No authentication provider for net.sf.acegisecurity.providers.UsernamePasswordAuthenticationToken

Then I thried to do it on behalf of admin. I used the call of AuthenticationUtils.startSession("admin", "admin"), but got another exception:

So, if someone is interested in it, I solved the problem after investigation these links:

All what I needed was to use "unproxied" SearchService and NodeService by determination the type of user.
