Hi, after a fresh installation of 2 fds server, i put them on replica; after, i tested that all was ok, i connect by web administration and i dicovered that : An error occurred while contacting the LDAP server. (Can't connect to the LDAP server) A connection to the server could not be opened. Contact your server administrator for assistance. whatever i do; on logs there is nothing expecial; all 2 server suffer the same issue; now i re-installed one of them and all is ok, on this one. On the other, the access and error logs under slapd-serverid/logs doesn't report anything during web acces Domain Manager login, on the admin-serv/logs i see: tail -f access 192.168.45.1 - - [04/Jul/2007:16:08:23 +0200] "GET /clients/dsgw/bin/lang?context=dsgw&file=clear.gif HTTP/1.1" 302 306 192.168.45.1 - - [04/Jul/2007:16:08:23 +0200] "GET /clients/dsgw/html/clear.gif HTTP/1.1" 200 43 192.168.45.1 - - [04/Jul/2007:16:08:21 +0200] "POST /clients/dsgw/bin/doauth HTTP/1.1" 200 798 192.168.45.1 - - [04/Jul/2007:16:08:31 +0200] "GET /favicon.ico HTTP/1.1" 403 282 192.168.45.1 - - [04/Jul/2007:16:08:31 +0200] "GET /favicon.ico HTTP/1.1" 403 282 tail -f error Wed Jul 04 16:08:31 2007] [notice] [client 192.168.45.1] admserv_host_ip_check: ap_get_remote_host could not resolve 192.168.45.1 [Wed Jul 04 16:08:31 2007] [error] [client 192.168.45.1] client denied by server configuration: /opt/fedora-ds/favicon.ico [Wed Jul 04 16:08:31 2007] [notice] [client 192.168.45.1] admserv_host_ip_check: ap_get_remote_host could not resolve 192.168.45.1 [Wed Jul 04 16:08:31 2007] [error] [client 192.168.45.1] client denied by server configuration: /opt/fedora-ds/favicon.ico these same eror are on the server ok. So, i argue that really admin-server is unable to contact ldap server in any way. What can be happened? Maurizio
