### User lookup

When a user provides their LDAP credentials, MinIO runs a lookup query to find the user's Distinguished Name (DN). The search filter and base DN used in this lookup query are configured via the following variables:

```
MINIO_IDENTITY_LDAP_USER_DN_SEARCH_BASE_DN*  (list)      ";" separated list of user search base DNs e.g. "dc=myldapserver,dc=com"

	errLikeInvalidEscape = errors.New("LIKE clause has invalid ESCAPE character")
	errNotImplemented    = errors.New("not implemented")
)

// AST Node Evaluation functions
//
// During evaluation, the query is known to be valid, as analysis is
// complete. The only errors possible are due to value type
// mismatches, etc.
//
// If an aggregation node is present as a descendant (when

		t.Fatal(err)
	}

	// Look for expected method.
	if res.Method != http.MethodGet {
