update madmin-go to v1.0.20

its possible that some multipart uploads would have
uploaded only single parts so relying on `len(o.Parts)`
alone is not sufficient, we need to look for ETag
pattern to be absolutely sure.

 ### Things to consider
-MinIO redirects browser access requests to the configured server port (i.e. `127.0.0.1:9000`) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URI. The URL and port *must* be accessible by the client for the redirection to work
+MinIO redirects browser access requests to the configured server port (i.e. `127.0.0.1:9000`) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URL. The URL and port *must* be accessible by the client for the redirection to work.
 
-For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the `MINIO_BROWSER_REDIRECT_URI` environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.
+For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the `MINIO_BROWSER_REDIRECT_URL` environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.
 
 For example, consider a MinIO deployment behind a proxy `https://minio.example.net`, `https://console.minio.example.net` with rules for forwarding traffic on port :9000 and :9001 to MinIO and the MinIO Console respectively on the internal network. Set `MINIO_BROWSER_REDIRECT_URL` to `https://console.minio.example.net` to ensure the browser receives a valid reachable URL.
 
+Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the `MINIO_SERVER_URL` environment variable  and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate.
+
+For example: `export MINIO_SERVER_URL="https://minio.example.net"`

 An IAM policy in JSON format that you want to use as an inline session policy. This parameter is optional. Passing policies to this operation returns new temporary credentials. The resulting session's permissions are the intersection of the canned policy name and the policy set here. You cannot use this policy to grant more permissions than those allowed by the canned policy name being assumed.

 ## Introduction
 
 MinIO provides a custom STS API that allows integration with LDAP based corporate environments including Microsoft Active Directory. The MinIO server can be configured in two possible modes: either using a LDAP separate service account, called lookup-bind mode or in username-format mode. In either case the login flow for a user is the same as the STS flow:

 If you set an empty lookup bind password, the lookup bind will use the unauthenticated authentication mechanism, as described in [RFC 4513 Section 5.1.2](https://tools.ietf.org/html/rfc4513#section-5.1.2).
 
+**Automatic LDAP sync:** In Lookup-Bind mode, the server periodically queries the LDAP service to:
+
+1. find accounts (user DNs) that have been removed;
+2. find accounts whose group memberships have changed.
+
+In case 1 above, any active STS credentials or MinIO service accounts belonging to these users are purged.
+
+In case 2 above, access policies available to the credential are updated to reflect the change - i.e. they will lose any privileges associated with a group they are removed from, and gain any privileges associated with a group they are added to.

 #### Username-Format Mode ####
 
-In this mode, the server does not use a separate LDAP service account. Instead, the username and password provided in the STS API call are used to login to the LDAP server and also to lookup the user's groups. This mode preserves older behavior for compatibility, but users are encouraged to use the Lookup-Bind mode.

This mode preserves older behavior for compatibility, but users are encouraged to use the Lookup-Bind mode. Some newer features may not be available in this mode of operation.
 
 The DN to use to login to LDAP is computed from a username format configuration parameter. This is a list of possible DN templates to be used. For each such template, the username is substituted and the DN is generated. Each generated DN is tried by the MinIO server to login to LDAP. If exactly one successful DN is found, it is used to perform the groups lookup as well.

 ## Introduction
 
-Calling AssumeRoleWithWebIdentity does not require the use of MinIO default credentials. Therefore, you can distribute an application (for example, on mobile devices) that requests temporary security credentials without including MinIO default credentials in the application. Instead, the identity of the caller is validated by using a JWT access token from the web identity provider. The temporary security credentials returned by this API consists of an access key, a secret key, and a security token. Applications can use these temporary security credentials to sign calls to MinIO API operations.

-Using the above `access_token` we can perform an STS request to MinIO to get temporary credentials for MinIO API operations. MinIO STS API uses [JSON Web Key Set Endpoint](https://docs.wso2.com/display/IS541/JSON+Web+Key+Set+Endpoint) to validate if JWT is valid and is properly signed.
