Hi Developer-Comunity, I'm using a Customer LDAP Backend to search for (internal) Customers. In our Identity-Management-System (Novell eDirectory) eachCustomer-Account is member of several groups (Attribute: GroupMembership). So, the Attribute "GroupMembership" is a Multivalued Attribute. I map this attribute via Config.pm ... $Self->{CustomerUser} = { Name => 'LDAP Backend', Module => 'Kernel::System::CustomerUser::LDAP', ... Map => [ # note: Login, Email and CustomerID needed! # var, frontend, storage, shown (1=always,2=lite), required, storage-type, http-link, readonly # [ 'UserTitle', 'Title', 'title', 1, 0, 'var', '', 0 ], [ 'UserFirstname', 'Firstname', 'GivenName', 1, 1, 'var', '', 0 ], [ 'UserLastname', 'Lastname', 'sn', 1, 0, 'var', '', 0 ], [ 'UserLogin', 'Username', 'uid', 1, 1, 'var', '', 0 ], [ 'UserEmail', 'Email', 'mail', 1, 1, 'var', '', 0 ], [ 'UserCustomerID', 'CustomerID', 'mail', 0, 1, 'var', '', 0 ], [ 'UserComment', 'Comment', 'groupMembership', 1, 0, 'var', '', 0 ], ], }; With ['UserComment', 'Comment', 'groupMembership', ...], I only can map the first value of the Multivalued Atribute "GroupMembership". How could I fetch the other values? According to a certain value of this attribut (e.g.: Customer is member of the LDAP-group "VIP-Support", GroupMembership: cn=VIP-Suport, o=Company, c=de) I would display this membership as follows: Search Result Username - Firstname Lastname - VIP-Support In addition, if clicking e.g. the link "Username", there should happen a certain action. Any ideas, how I can fetch all values of an LDAP-Multivalue attribute and work with a certain value? Thanks in advance. Jo
