The error is: "The specified domain either does not exist or could not be
contacted ", and is thrown by the FindOne() method.
The path I'm using looks like LDAP://company.com/CN=My Name,OU=User
Accounts,OU=Accounts,DC=company,DC=com

This is the method I'm using to get the user's groups:

public string GetGroups()
{
DirectorySearcher search = new DirectorySearcher(_path);
search.Filter = "(cn=" + _filterAttribute + ")";
search.PropertiesToLoad.Add("memberOf");
StringBuilder groupNames = new StringBuilder();

SearchResult result = search.FindOne();
int propertyCount = result.Properties["memberOf"].Count;
int equalsIndex, commaIndex;

for( int i = 0; i < propertyCount; i++)
                                {
String dn = (String)result.Properties["memberOf"][i];

equalsIndex = dn.IndexOf("=", 1);
commaIndex = dn.IndexOf(",", 1);
if (-1 == equalsIndex)
{
return null;
}
groupNames.Append(dn.Substring((equalsIndex + 1), (commaIndex - equalsIndex)
- 1));
groupNames.Append("|");
}
return groupNames.ToString();
}
