# Basic Authentication - LDAP

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

## 1.4.2

**October 1, 2026**

### What’s New

- This release updates policy metadata only. There’s no functional change.

## 1.4.0

**July 29, 2022**

### What’s New

- The policy definition and policy implementation file are now separate. This enables stronger
  validations for policy configuration parameters.

## 1.3.1

**Apr 30, 2020**

### Minimum Mule Version

**Mule 4.1.0**

### New Features and Enhancements

- Error handling responses revised for WSDL APIs to be compliant with SOAP 1.1 and 1.2.

- Performance improvements are introduced to the header manipulation engine.

### Fixed issues

- After a policy was applied, HTTP headers did not follow the RFC 2616 requirement of
  case-sensitivity:

  [https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2](https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2).

## 1.3.0

**Jul 26, 2019**

### Minimum Mule Version

**Mule 4.1.0**

### New Features and Enhancements

- Several performance improvements are introduced in this release.

- Improved error handling for LDAP server validation errors and user authentication errors with
  appropriate error messages. The application generated a 401 error for both LDAP server
  authentication problems and incorrect user credentials provided by the user. The application now
  generates error 500 for LDAP server authentication errors. When incorrect user credentials are
  provided, error 401 is generated.

### Known Issues

- An error occurs in Mule versions v4.1.1, v4.1.2, 4,1,3 and 4.1.4 when a policy is deployed to
  applications that have the mule-secure-configuration-property-module plugin configured. To resolve
  this issue, upgrade the specified plugin in the application to version 1.1.0.

## 1.2.0

**Apr 26, 2019**

### Minimum Mule Version

**Mule 4.1.0**

### New Features and Enhancements

- Introduced support to encrypt sensitive information related to the policy. The Runtime version
  must be properly configured and must support encryption. Encryption is supported starting with
  Mule Runtime v4.2.0.

- Several performance improvements are introduced.

- Reduced policy weight.

### Known Issues

- An error occurs in Mule versions v4.1.1, v4.1.2, 4,1,3 and 4.1.4 when a policy is deployed to
  applications that have the mule-secure-configuration-property-module plugin configured. To resolve
  this issue, upgrade the specified plugin in the application to version 1.1.0.

### Fixed Issues

When a WSDL proxy received an empty payload, or an invalid XML, an ExpressionRuntimeException error
was generated. This issue is now resolved.

## 1.1.1

**Jun 25, 2018**

### Minimum Mule Version

**Mule 4.1.0**

### New Features and Enhancements

Added `violationCategory` in the YAML configuration for Feedback Loop.

## 1.1.0

**Jan 25, 2018**

### Minimum Mule Version

**4.0.0**

### New Features and Enhancements

- Added subtree search scope.

- Reduced error-handling verbosity in templates.

### Fixed Issues

- Improved error message verbiage for the invalid server scheme error.

- When an Authorization header is malformed, a 500 status code was returned instead of 401. This
  issue is now resolved.

## 1.0.0

**Nov 17, 2017**

### Minimum Mule Version

**4.0.0**
