Microsoft memperbaiki masalah autentikasi Windows Kerberos dalam pembaruan darurat

November 18, 2022 by Eevee

Microsoft telah merilis pembaruan out-of-band (OOB) opsional untuk memperbaiki masalah yang memicu kegagalan masuk Kerberos dan masalah autentikasi lainnya pada pengontrol domain Windows setelah menginstal pembaruan kumulatif yang dirilis selama Patch Selasa November.

Microsoft mengakui dan mulai menyelidiki pada hari Senin dan mengatakan bahwa masalah yang diketahui dapat memengaruhi skenario autentikasi Kerberos apa pun dalam lingkungan perusahaan yang terpengaruh.

“Saat masalah ini terjadi, Anda mungkin menerima peristiwa kesalahan Microsoft-Windows-Kerberos-Key-Distribution-Center Event ID 14 di bagian Sistem Log Peristiwa pada Pengontrol Domain Anda dengan teks di bawah ini.”

Daftar skenario autentikasi Kerberos yang terpengaruh mencakup namun tidak terbatas pada hal berikut:

  • Login pengguna domain mungkin gagal. Ini juga dapat mempengaruhi autentikasi Active Directory Federation Services (AD FS).
  • Akun Layanan Terkelola Grup (gMSA) yang digunakan untuk layanan seperti Layanan Informasi Internet (Server Web IIS) mungkin gagal diautentikasi.
  • ​Koneksi Desktop Jarak Jauh menggunakan pengguna domain mungkin gagal tersambung.
  • ​Anda mungkin tidak dapat mengakses folder bersama di workstation dan berbagi file di server.
  • ​Pencetakan yang memerlukan autentikasi pengguna domain mungkin gagal.

Microsoft merilis pembaruan darurat OOB yang harus diinstal oleh admin Windows di semua Pengontrol Domain (DC) pada lingkungan yang terpengaruh.

Pembaruan OOB tersedia melalui Katalog Pembaruan Microsoft dan tidak akan ditawarkan melalui Pembaruan Windows.

Redmond telah merilis pembaruan kumulatif untuk penginstalan di Pengontrol Domain (tidak diperlukan tindakan di sisi klien):

  • Windows Server 2022: KB5021656
  • Windows Server 2019: KB5021655
  • Windows Server 2016: KB5021654

Microsoft juga merilis pembaruan mandiri yang dapat diimpor ke Windows Server Update Services (WSUS) dan Microsoft Endpoint Configuration Manager:

  • Windows Server 2012 R2: KB5021653
  • Windows Server 2012: KB5021652
  • Windows Server 2008 SP2: KB5021657

Satu-satunya platform yang terpengaruh yang masih menunggu perbaikan adalah Windows Server 2008 R2 SP1. Redmond mengatakan bahwa pembaruan khusus akan tersedia minggu depan.

Anda dapat menemukan instruksi penyebaran WSUS terperinci di WSUS dan instruksi Pengelola Konfigurasi dan Situs Katalog di halaman Impor pembaruan dari halaman Katalog Pembaruan Microsoft.
