<HTML><HEAD></HEAD><BODY><P>The error message indicates the system is looking for an LDAP server named domaincontroller.company.com.</P><P></P><P>Your ldap-auth props file has the naming provider URL, although in the file you attached it just says IP<img id="smileytongue" class="emoticon emoticon-smileytongue" src="https://connect.hyland.com/i/smilies/16x16_smiley-tongue.png" alt="Smiley Tongue" title="Smiley Tongue" />ort, so I don't know if that's the real one you are using (seems unlikely) or if you changed it prior to uploading.</P><P></P><P>In any case, it is different than what the error message indicates, so I suspect you don't have your file in the right place and Alfresco is using the default.</P><P></P><P>Where are you putting that file? It should go in the proper subsystem structure in $ALFRESCO_HOME/tomcat/shared/classes/alfresco/extension/subsystems/Authentication/ldap-ad/ldap-ad1. Alternatively, you could just copy all of those LDAP properties into your alfresco-global.properties file.</P></BODY></HTML> Thu, 15 Nov 2018 16:42:01 GMT https://connect.hyland.com/t5/alfresco-forum/org-alfresco-repo-security-authentication-ldap/m-p/67422#M22514 jpotts 2018-11-15T16:42:01Z
