RBAC: Support Active Directory

[Haarolean]

LdapSecurityConfig:

• verify ActiveDirectoryLdapAuthenticationProvider does populate authorities properly (most likely, it doesn't)
• if it doesn't, copy-paste ActiveDirectoryLdapAuthenticationProvider
  and (re)implement a populator (unless #4490 is resolved)

via provectus/kafka-ui#3741

[Haarolean]

the last part might be fixed pretty soon in spring-projects/spring-security#14539, so we might want to put this on hold.
