The listener checkbox was checked up to listen for changes on the fly.CauseThe LDAP server in use is Microsoft Active Directory. However, at LDAP record creation time the 'vendor' was set to 'Other' instead of 'Active Directory'. ResolutionOpen the LDAP Server record that you have issues with. Right Click on the record banner and select Configure > Form Layout.From the list of fields, add the field 'vendor' into the first section of the form.Save the form.Now that you have the Vendor field added in the form, change the vendor type to 'Active Directory'.Save the record.Stop the Listener. The listener will be probably left in an error state after stop it. Follow these steps: a. Navigate to each LDAP Server and click Stop Listener. b. Delete the *glide.ldap.listener entries in the sys_status table (details c and d) c. Enter sys_status.list in the filter. d. Search for the name *glide.ldap.listener. e. Delete the entries.Navigate to each LDAP Server and click Start ListenerIf you use a MID server for LDAP, restart it now.Test the LDAP connection to verify that there is connection to the LDAP server.Start the listener again. You may remove the 'vendor' field from the LDAP form.Related LinksA listener is a dedicated process that periodically searches for changes on the LDAP server. The listener can be deployed on a Microsoft Active Directory server that supports persistent queries (ADNotify), or on an LDAP server that supports persistent search request control (OID 2.16.840.1.113730.3.4.3). Selecting the correct LDAP type at record creation will set the correct Listener protocol to use.
