I had the same problem. I found the solution in this post: https://communities.coverity.com/thread/1947 . You must replace the blanks in the DN of the URL of the ldap-server in the bean "ldapContextSource" in your applicationContext-externalAuth-LDAP.xml. So it looks like this: <bean id="ldapContextSource" class="com.jaspersoft.jasperserver.api.security.externalAuth.ldap.JSLdapContextSource"> <constructor-arg value="ldap://<server>:389/dc=<example>,dc=de"/> <property name="userDn" value="cn=<user>,ou=<usergroup>,dc=<example>,dc=de"/> <property name="password" value="<password>"/> </bean> I hope this helps you.
