Unable to connect to LDAP, verify your credentials #10

anasbousselham · 2022-02-16T23:46:56Z

Hi,
It's possible to used it without ldap flags.?!
Thanks

yellow-starburst · 2022-02-17T01:11:13Z

yes it is possible to be used without ldap flags.
Can you close the ticket now?

anasbousselham · 2022-02-17T01:23:41Z

I have this error without any flag!

rvazarkar · 2022-02-17T15:45:45Z

Are you running this through netonly? Do you have a proper domain authentication?

x3rz · 2022-02-19T08:51:44Z

I have this error without any flag!

Same issue for me without supplying any creds it is showing me that error

gabemarshall · 2022-02-24T18:15:32Z

@rvazarkar I'm also experiencing this. I'm running it through netonly and have proper domain auth (Powerview works fine, old versions of Invoke-Bloodhound work).

lungdart · 2022-02-24T21:54:52Z

Same situation here on the HTB forest machine.

When I checkout the old version of SharpHound from the bloodhound repo commit 6a95882e0e88c398f97f2a82a956eef5b3b10ae8, the identical command works (But then starts throwing stack traces later on)

I guess I'll keep going back into the commits until I can find a stable version...

walterone · 2022-02-28T19:28:35Z

still got the same issue, has anyone found a workaround yet?

rvazarkar · 2022-02-28T19:50:08Z

        ///     Tests the current LDAP config to ensure its valid by pulling a domain object
        /// </summary>
        /// <returns>True if connection was successful, else false</returns>
        public bool TestLDAPConfig(string domain)
        {
            var filter = new LDAPFilter();
            filter.AddDomains();

            var resDomain = GetDomain(domain)?.Name ?? domain;
            
            var result = QueryLDAP(filter.GetFilter(), SearchScope.Subtree, CommonProperties.ObjectID, resDomain)
                .DefaultIfEmpty(null).FirstOrDefault();

            return result != null;
        }

This is how we test for a valid LDAP connection: we query for domain objects and make sure we can get at least one. For whatever reason, that test is failing and we're getting nothing back. If you run with -v 0 it might give you some more insight as to where the check is failing, you can report back with that information

walterone · 2022-03-01T09:41:09Z

The verbose option only shows the TRACE info of the "TestConnection link" in the TestConnection() Function.

Using powershell AD functionality and/or powerview it's possible to retrive objects in the domain.
Also it looks like that the issue is mainly related to the HTB Forest machine, i still have to try in other environments

rvazarkar · 2022-03-02T19:20:35Z

I beleive I know whats causing this, I'll have a new build soon

YB1-cyber · 2022-03-04T14:24:16Z

@rvazarkar
I joined the "unable to connect to LDAP" club , and also a friend of mine...
so if you can update here , it'll nice

BTW
I wonder:
A) Can you tell why the .ps1 collector had been removed ?
B) Will SharpHound.ps1 support the new format (matching bloodhound 4.1+) when we get it back ?

rvazarkar · 2022-03-07T17:18:09Z

Should be fixed in v1.0.3. Reopen if the problem is still there

@YB1-cyber it was removed because I ran out of time when doing this release, and yes it will

chinformer · 2022-03-18T16:27:16Z

Hey, I can confirm this is still affecting v1.0.3. I've just compiled the -dev 1.0.3 version (x64) no other changes and when supplying --ldapusername and --ldappassword the error is:

Same issue with 1.0.3 (x64)

chinformer · 2022-04-19T08:15:06Z

@rvazarkar any update on the potential fix for this? I added the original comment on the 18th March 2022 :). Thank you

rvazarkar · 2022-04-19T15:46:05Z

Open a new issue, and use -v 0 to get verbose logging so I can see where the issue is happening

@rvazarkar any update on the issue and whether the changes have been made? I commented a while back (in Apr)

@pkyria14, I had to reboot the windows machine to get this command to work.

Is this issue a dupe of something or should it be reopened if still unresolved 😌

JonasBK · 2024-01-31T19:53:43Z

Hi @BaronSam3di,
Try the latest SharpHound version here: https://github.com/BloodHoundAD/SharpHound/releases/latest

stuartw1 · 2024-03-18T15:45:54Z

I had this error message today. My target environment had 389 disabled and 636 open for LDAPS

I used the -SecureLDAP flag, but this didnt work and returned an "unable to connect to LDAP" error until I tried -DisableCertVerification and -DisableSigning, which made it work perfectly. Interestingly I had to provide domain, ldapusername and ldappassword too, with ldapusername set to [email protected] rather than INTERNAL\user.name

Perhaps the error message could be expanded - either to include if it is a connection security fault, or to suggest trying flags that drop security validation measures if appropriate. It would be good if the logs contained the port that was being tried also.

vcap-kali · 2024-04-03T20:59:56Z

This is what worked for me: adding the two LDAP flags and changing the username from DOMAIN\username to [email protected]

StavrosCaptain · 2024-07-30T09:22:51Z

If you have problem with Sharphound as above, do the following (example from sauna machine in HTB):

a) bloodhound-python -u svc_loanmgr -p '<PASSWORD>' -d EGOTISTICALBANK.LOCAL -ns 10.10.10.175 -c All
b) zip info.zip *.json
c) drag&drop the .zip file in BloodHound

To install bloodhound-python:
sudo apt install bloodhound
sudo pip install bloodhound-python

PurpleLinux · 2024-10-25T01:03:02Z

Just a quick note to anyone perusing, if you don't ad the -d <domain> flag, you will also get this error
