The LDAP server is unavailable

Question

I'm a total newbie to this

Trying to connect to an ldap server with PrincipalContext. I have tried all solutions on this site to no avail.

Things I've tried:

PrincipalContext insPrincipalContext = 
   new PrincipalContext(ContextType.Domain);

PrincipalContext insPrincipalContext = 
   new PrincipalContext(ContextType.Domain, "ldap://localhost:389/dc=maxcrc,dc=com");

PrincipalContext insPrincipalContext = 
   new PrincipalContext(ContextType.Domain, "maxcrc.com");

All give the same result:

LDAP server not available

Only ContextType.Machine works basically.

Not sure if my LDAP server is set up correctly:

• Host: localhost
• Port: 389
• Base DN: dc=maxcrc,dc=com
• URL: ldap://localhost:389/dc=maxcrc,dc=com

Testing with Softerra LDAP Browser

Any tutorials from start to finish will be much appreciated...

Answer 1

I have been facing the same issue and I found a solution.

I'm able to connect easily using following code:

 ADUser_Id = "domainName\\username"; //make sure user name has domain name.
 Password = "xxxx";
var context = new PrincipalContext(ContextType.Domain,"server_address", ADUser_Id,Password);
/* server_address = "192.168.15.36"; //don't include ldap in url */
