When searching for users or groups after configuring Integrated Windows Authentication (IWA) for a portal, the following error message is returned:

Error:   
LDAP: error code 1 - 000004DC: Ldaperr: DSID-0C0907C2, comment: In order to perform this operation a successful bind must be completed on the connection.

The information provided in the security configuration JSON file is not reaching out to the correct machine because the parameter for the domain controller is not specified.

After configuring IWA for the portal, access the security configuration JSON file and update the domainControllerAddress parameters. Refer to Portal for ArcGIS: Configure the domain controller used by Portal for ArcGIS for steps to do this.

LDAP error: 000004DC: LdapErr: DSID-0C0906E8 #736

I try to use NIPAP with LDAP authentication, but when I try to login with my Active Directory credentials I get the following error:

I only get the above error when I enter valid credentials. If I enter a valid user, but a incorrect password I get the following error: Invalid username or password.

So maybe NIPAP communicate with the Domain Controller, but then fail with something.

My NIPAP LDAP config is:

[auth]
default_backend = ldap ; which backend to use by default
auth_cache_timeout = 3600 ; seconds cached auth entries are stored

[auth.backends.local]
type = SqliteAuth

db_path = /etc/nipap/local_auth.db ; path to SQLite database used

[auth.backends.ldap]
type = LdapAuth

basedn = dc=my,dc=domain,dc=com ; base DN
uri = ldap://dc1.my.domain.com ; LDAP server URI
tls = False ; initiate TLS, use ldap://

binddn_fmt = <>@my.domain.com
search = sAMAccountName=<>

I try to use NIPAP authentication with a Microsoft Active Directory Forest Functional Level: Windows Server 2008 R2.

I have python-ldap installed and NIPAP works fine with local authentication.

I have tried to set the following in: /etc/openldap/ldap.conf:
HOST DC1.my.domain.com
PORT 636
TLS_REQCERT demand

But it did not solve the error.

Thanks in advance.

Question

For our application we are trying to use AD for User Authentication. While trying to do the User Authentication we get the following error

LDAP: error Code 1 — 000004DC: LdapErr: DSID-0C09072B, comment: In order to perform this operation a successful bind must be completed on the connection., data 0, v2580

We have given an Authentication base too.

Can somebody please help us in deciphering the error code DSID-0C09072B? Why does this error code occur?

Have a nice day
Amardeep

Answers

It seems that you mixed the authentication with the LDAP querying. Before being able to do queries and use LDAP filters, you need to see how to authenticate yourself using a service account.

So, you need to create an AD user account that you will be using as a service account and then see on the application level how to use the service account for authentication.

вот мой файл настроек

` # URL-адрес сервера LDAP. LDAP_AUTH_URL = «ldaps://пример.com:636»

Есть идеи, что я делаю не так?

Комментарии:

1. Для выполнения этой операции необходимо выполнить успешную привязку соединения : вам необходимо установить LDAP_AUTH_CONNECTION_USERNAME и LDAP_AUTH_CONNECTION_PASSWORD , в противном ldap_sync_users случае команда выполнит анонимный запрос (ваш сервер не принимает анонимную привязку).

Ответ №1:

Я не знаю Джанго, но я вижу пару вещей:

Согласно документации, которую я видел, это не должен быть URL-адрес. Это должно быть просто доменное имя вашего рекламного домена, вот так:

Это означает, что вы пытаетесь выполнить анонимную привязку, которую большинство доменов не разрешат.

Комментарии:

1. Спасибо, наконец, я решил эту проблему с некоторыми другими незначительными изменениями

Post by ghostadmin » Sat Apr 27, 2019 8:15 pm

auth-ldap.conf is were the fun starts

1. 389 vs 636
with:
URL «ldap://192.168.3.12:389»
TLSEnable no
BindDN «cn=openvpn,ou=ServiceAccounts,ou=x,ou=x,dc=ad,dc=myorg,dc=com»

the connection is working but i want to use encrypted connection. AD is already equiped with CA. So i changed to:
URL «ldap://192.168.3.12:636»
TLSEnable yes

but then the connection fails:
«Unable to enable STARTTLS»
Also TLSEnable no and/or ldaps://192.168.3.12 is not working.
I can connect with LDAP Browser providing same details just fine, server is working on 389 and 636, but why cant i secure connect with openvpn. I dont to specify any extra cert files, shouldnt OpenVPN just accept the self signed cert? Do i really need to export them certificates from AD ? Also i want to use 2 domain controllers to connect.

In almost all examples i found it is specified as cn=users,dc=domain,dc=com» which is working for any users there but i have different structure so tried to scope everything with dc=ad,dc=myorg,dc=com. But no users are working.
What do i need to specify if i got users in:
cn=users,dc=ad,dc=myorg,dc=com
and
ou=users,ou=x,ou=x,dc=ad,dc=myorg,dc=com

same goes for RequireGroup, also not working

Question

I am being tasked with disabling anonymous access to our AD servers. I found the link below and using the link I went to the dSHeuristics attribute and it is » » . Do I need to place a zero there to disable it?

Answers

LDAP anonymous access is disabled since Windows Server 2003. So if your dSHeuristics key is not set, you just don’t have anonymous access enabled for LDAP.

Give it a try! Open LDP.EXE, click on Connect, type the FQDN of the DC and click Connect. Then click on Bind, select simple bind, type for example: Anonymous in the user field and leave the password field blank:

You should see this in the output section of LDP:

res = ldap_simple_bind_s(ld, ‘Anonymous’, ); // v.3

Authenticated as: ‘NT AUTHORITYANONYMOUS LOGON’.

Now if you try to browse the directory (for example go to View > Tree and pick the default naming context), if Anonymous bind is disabled, you should see this message:

Expanding base ‘DC=fabrikam,DC=com’.

ldap_get_next_page_s failed: 1

Getting 0 entries:

BUT, LDAP is just one way to access to the DC anonymously. So even if this one is in fact disabled, also check the following settings for RPC and Named Pipes access:
