LDAP server error: LDAP Result Code 200 "Network Error": EOF | Login getting failed with 401(Unauthorized) status code

Expected Behavior

Login to Minio console should be working fine with LDAP Identity provider.

Current Behavior

Login to Minio console is getting failed with LDAP Result Code 200 "Network Error": EOF

Possible Solution

No solution. Workaround to access the Minio Console would be to use Built-In Identity provider.

Steps to Reproduce (for bugs)

Context

LDAP / AD Users are unable to login to Minio Console.

@Sanketbhandare Post your setup steps. plz

[Sanketbhandare]

1. Create a new Tenant using Minio Operator
2. Under Identity Provider Section, Choose "LDAP / Active Directory" option and provide information related to your LDAP server.
3. Once you provide all the necessary information like Lookup Bind DN, Lookup Bind Password, User DN Search Base DN, User DN Search filter etc.
4. Once done, save your changes.
5. Open Minio Console session for newly created tenant & try login to Minio console via your AD Account.
6. Ideally you should be able to login, But It's failing with above Network Error in our case.

@jiuker Any update on this?

[jiuker]

Yeah. @Sanketbhandare Found that.

[jiuker]

Maybe you need config MINIO_IDENTITY_LDAP_SERVER_INSECURE = on

[jiuker]

Please follow this https://min.io/docs/minio/linux/reference/minio-server/settings/iam/ldap.html, MINIO_IDENTITY_LDAP_SERVER_INSECURE

[Sanketbhandare]

@jiuker We've been following the same setting since start, but we're still getting the 401 Unauthorized response.
We're using below config along with base DN & LDAP details(Confidential).

MINIO_IDENTITY_LDAP_GROUP_SEARCH_FILTER: (&(objectclass=groupOfNames)(member=%d))
MINIO_IDENTITY_LDAP_SERVER_INSECURE: on
MINIO_IDENTITY_LDAP_SERVER_STARTTLS: off
MINIO_IDENTITY_LDAP_TLS_SKIP_VERIFY: on
MINIO_IDENTITY_LDAP_USER_DN_SEARCH_FILTER: (uid=%s)

Minio Operator version: 5.0.12

LDAP_SERVER running with tls or not ? @Sanketbhandare

[Sanketbhandare]

@jiuker LDAP_SERVER is running without tls

[jiuker]

No idea for that. I can't reproduce that. @Sanketbhandare Check the server's log.
