I'am installing ArcGisServer for the Java plataform on Centos 5.5 x86_64, this is not a supported platform but I have overcome almost every problem preventing the success of the installation. It uses exhaustively Sun Directory Server. The last error i receive was:

ldap_simple_bind: Can't connect to the ldap server - No route to host

It happens in other applications which makes uses of it, so it seems to be an specific problem of Sun Directory Server on linux and solaris. There is no reported solution. Usually I search the problem as much as I can but this time I have reached my patience and I need it working as soon as posible. I recognize this as an excellent forum because of it's community and quality of answers, ¿can anybody help me with this?

The "No route to host" error suggests that the issue is one of network connectivity between your ArcGIS server (the Sun Directory Server component, as you mention) and the LDAP server. So, a few things to examine, in order:

1. Do you have an LDAP server set up and running?
2. Is your LDAP server reachable from your Centos machine outside of the ArcGis server?

3. Is your ArcGis configured with the correct address to the LDAP server - should be in the web.config file? Example below:

   <connectionStrings>

   <add name="ADConnectionString" connectionString="LDAP://SERVER_LDAP:389/ou=Sigestredi,o=Sicondef,dc=aplicaciones,o=mdef,c= es" />

   </connectionStrings>

   • Disclaimer: I don't know anything about the ArcGIS server per se - I'm just diagnosing the "no route to host error" with a few snippets I picked up from some quick searches of the ArcGis forums.
