Describe the bug Encountering an endless Authentication loop with Spring Security version 6.2.2 when incorrect LDAP credentials are provided. This occurs in a custom AuthenticationProvider that utilizes ActiveDirectoryLdapAuthenticationProvider. The error stems from recursive calls between an AuthenticationProvider and its parent, similar to issues discussed in related threads and #4203.

To Reproduce

  1. Configure ActiveDirectoryLdapAuthenticationProvider in a custom AuthenticationProvider.
  2. Implement a condition within the custom provider that leads to delegation to a parent AuthenticationProvider.
  3. Attempt LDAP authentication with an incorrect password.

Expected behavior is expected to gracefully handle incorrect LDAP authentication attempts by throwing an AuthenticationException, not an Endless Authentication Loop , due to recursive provider delegation.
