We have the same issue with Samba 4.13.17. For Ubuntu 20.04 with Samba 4.13.17 there seems to be only a workaround to solve the login problem: Modifying the Local Security Policy -> Local Policies -> Security Options -> Network security: "Configure encryption types allowed for Kerberos" Check only DES_CBC_CRC, DES_CBC_MD5 and RC4_HMAC_MD5. ? This worked for us to login again. ?
