LDAP synchronization problem

Question asked by johnk on Apr 28, 2008
Latest reply on Apr 29, 2008 by dinger
Hello mates,

I'm having trouble enabling LDAP sync + chaining on alfresco community 2.1.

Actually made it so alfresco recognises it's own users and also LDAP ones, whose get registered in alfresco after their first login (Also had some problems making new users in alfresco but those got solved). But I need to enable sync too, so each X seconds alfresco imports all LDAP users overwriting if necesary.

My files are:

chaining-authentication-context.xml

    <!–
       
    There can be more than one stack of beans that import users or groups. For example, it may be easier
    to have a version of ldapPeopleExportSource, and associated beans, for each sub-tree of your ldap directory
    from which you want to import users. You could then limit users to be imported from two or more sub tress and ignore
    users found else where. The same applies to the import of groups.

        The query to select objects that represent the users to import.

        THIS MUST MATCH WHAT THE USER TYPES IN AT THE LOGIN PROMPT   
       
        For simple LDAP authentication this is likely to be "cn" or, less friendly, "distinguishedName"
       
        In OpenLDAP, using other authentication mechanisms "uid", but this depends on how you map
        from the id in the LDAP authentication request to search for the inetOrgPerson against which
        to authenticate.
       
        In Active Directory this is most likely to be "sAMAccountName"
