132132 Utilities like Active Directory Administrative Center (ADAC), Active Directory Users and Computers (ADUC), `net computer`, and `dsmod` also honor this new behavior. Both ADAC and ADUC no longer allow creation of a pre-Windows 2000 account.

134134 - **Kerberos PKINIT support for cryptographic agility**: The Kerberos Public Key Cryptography for Initial Authentication in Kerberos (PKINIT) protocol implementation is updated to allow for cryptographic agility by supporting more algorithms and removing hardcoded algorithms.

135 −- **Kerberos changes for Algorithms used for Ticket Granting Tickets**: The Kerberos Distribution Center will no longer issue Ticket Granting Tickets using RC4 encryption, such as RC4-HMAC(NT).

135 +- **Kerberos changes for Algorithms used for Ticket Granting Tickets**: The Kerberos Distribution Center will no longer issue Ticket Granting Tickets using RC4 encryption, such as RC4-HMAC(NT).

136 +- **Kerberos changes for supported encryption type configuration**: Kerberos will no longer honor the legacy registry key REG_DWORD `SupportedEncryptionTypes` found under `HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Lsa\Kerberos\Parameters`. Microsoft recommends to leverage the group policy [Network security: Configure encryption types allowed for Kerberos

137 +](https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-10/security/threat-protection/security-policy-settings/network-security-configure-encryption-types-allowed-for-kerberos) instead.

136138 - **LAN Manager GPO setting**: The GPO setting **Network security: Don't store LAN Manager hash value on next password change** is no longer present and doesn't apply to new versions of Windows.

137139 - **LDAP encryption by default**: All LDAP client communication after a Simple Authentication and Security Layer (SASL) bind uses LDAP sealing by default. To learn more about SASL, see [SASL Authentication](/openspecs/windows_protocols/ms-adts/989e0748-0953-455d-9d37-d08dfbf3998b).

138140 - **LDAP support for Transport Layer Security (TLS) 1.3**: LDAP uses the latest SCHANNEL implementation and supports TLS 1.3 for LDAP over TLS connections. Using TLS 1.3 eliminates obsolete cryptographic algorithms and enhances security over older versions. TLS 1.3 aims to encrypt as much of the handshake as possible. To learn more, see [Protocols in TLS/SSL (Schannel SSP)](/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-) and [TLS Cipher Suites in Windows Server 2022](/windows/win32/secauthn/tls-cipher-suites-in-windows-server-2022).
