Running v3.1 of the SQL Server Kerberos Configuration Manager (KerberosConfigMgr) on Windows Server 2012 against a SQL Server Developer 2016 instance on same server.
Running tool as admin (logged in to server as domain admin account).
Default blank details specified in the Kerberos tool. I have also tried entering details of another server running same version of SQL along with my domain admin user account details, with same result.
The application thinks for about 10 seconds then responds with error message "Unable to access User Principal information from the System"
Log has the following:
10/31/2017 2:41:09 AM Error: Access of User Principal information failed System.DirectoryServices.AccountManagement.PrincipalServerDownException: The server could not be contacted. ---> System.DirectoryServices.Protocols.LdapException: The LDAP server is unavailable. at System.DirectoryServices.Protocols.LdapConnection.Connect() at System.DirectoryServices.Protocols.LdapConnection.SendRequestHelper(DirectoryRequest request, Int32& messageID) at System.DirectoryServices.Protocols.LdapConnection.SendRequest(DirectoryRequest request, TimeSpan requestTimeout) at System.DirectoryServices.AccountManagement.PrincipalContext.ReadServerConfig(String serverName, ServerProperties& properties) --- End of inner exception stack trace --- at System.DirectoryServices.AccountManagement.PrincipalContext.ReadServerConfig(String serverName, ServerProperties& properties) at System.DirectoryServices.AccountManagement.PrincipalContext.DoServerVerifyAndPropRetrieval() at System.DirectoryServices.AccountManagement.PrincipalContext..ctor(ContextType contextType, String name, String container, ContextOptions options, String userName, String password) at System.DirectoryServices.AccountManagement.PrincipalContext..ctor(ContextType contextType, String name) at KerberosCM.WMIHelper.TryGetUser(SystemInfo mi, UserPrincipal& user)
As a test, I have successfully run ADFind to get a listing of admin users from the default DC.
I have tried all solutions from this post to no avail (no orphaned GUID users in local administrators group, run tool as a different user account) Kerberos Configuration Manager for SQL Server error "unable to access user principal information from the system"
Any ideas what else I can do here?
