## Introduction

MinIO provides a custom STS API that allows integration with LDAP based corporate environments including Microsoft Active Directory. The MinIO server uses a separate LDAP service account to lookup user information. The login flow for a user is as follows:

- User provides their AD/LDAP username and password to the STS API.
- MinIO looks up the user's information (specifically the user's Distinguished Name) in the LDAP server.

        // create a buffer with count = 0x1234 (4660 decimal)
        // Using little-endian byte order as per SMBUtil.readInt2
        byte[] buf = new byte[12];
        buf[0] = 0x34; // Low byte
        buf[1] = 0x12; // High byte
        int written = resp.readParameterWordsWireFormat(buf, 0);

        assertEquals(8, written, "Expected readParameterWordsWireFormat to advance 8 bytes");

	}
	return p.roleArn.String()
}

// UserInfo returns claims for authenticated user from userInfo endpoint.
//
// Some OIDC implementations such as GitLab do not support
// claims as part of the normal oauth2 flow, instead rely
// on service providers making calls to IDP to fetch additional
// claims available from the UserInfo endpoint

may occasionally increase the size of the cluster a bit more than it is actually needed, when there are
unschedulable pods, scale up is required and cloud provider is slow to set up networking for new nodes.
Anyway, the cluster should get back to the proper size after 10 min.

# The following variable is used to tell the kernel how 
# much of the socket buffer space should be used for TCP 
# window size, and how much to save for an application buffer.

API, and MinIO verifies this token by sending it to the Identity Management Plugin webhook. This plugin responds with some information and MinIO is able to generate temporary STS credentials to interact with object storage.

The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT: There is no console UI integration for this method of authentication and it is intended primarily for machine authentication....
