Hey,

i would like to configure alfresco with chaining in order to keep both alfresco internal users i created (such as the admin/admin account) and my ldap users.
Could u please tell me what to edit in the chaining-authentication-context.xml

Same issue here. Looking for a working chaining-authentication-context.xml file for ldap authentication in alfresco 3 b.

houlnx

I am getting the following error with these 2 files. I have read only access to ldap authentication.

    <!– LDAP authentication configuration –>

    <!–

    You can also use JAAS authentication for Kerberos against Active Directory or NTLM if you also require single sign on from the
    web browser. You do not have to use LDAP authentication to synchronise groups and users from an LDAP store if it supports other
    authentication routes, like Active Directory.

            This maps between what the user types in and what is passed through to the underlying LDAP authentication.

            "%s" - the user id is passed through without modification.
            Used for LDAP authentication such as DIGEST-MD5, anything that is not "simple".

            "cn=%s,ou=London,dc=company,dc=com" - If the user types in "Joe Bloggs" the authenticate as "cn=Joe Bloggs,ou=London,dc=company,dc=com"
            Usually for simple authentication. Simple authentication always uses the DN for the user.
