LDAP certificates Uploading an SSL certificate allows the instance to establish an LDAP over SSL (LDAPS protocol) connection with an LDAP server. The instance accepts two types of LDAP certificates: Table 1. LDAP certificates Certificate Type Required for LDAP server certificate Any supported type All LDAP configurations LDAP client certificate Java keystore type Mutual authentication If there are multiple server certificates, ServiceNow tries each server certificate in turn until the LDAP server allows the connection. If you use multiple LDAP servers, be sure to include the SSL certificate for each LDAP server. If your LDAP server requires mutual authentication (requires the client to present a certificate in addition to the server), you must also provide your LDAP server's client certificate in a Java keystore type certificate.
