Hi list, According to the doc, CustomerIDs can be pulled from a LDAP customer backend if the declared attribute contains a list of customer ids separated by commas. (see http://doc.otrs.org/3.2/en/html/external-backends.html#multi-customer-ids-ld...) We use an ActiveDirectory as user repository an plan to use the directReports/manager attributes. That is, for a manager, asking for the directReports attribute return a list of reporters. Is it possible to set the LDAP attribute to an attribute that returns multiple values ? I guess if not, I should try to adapt Kernel/System/CustomerUser/LDAP.pm for that purpose by myself ?
