Anyway, thanks a lot for your help.
I've found few discusions about similar problems:
https://docs.active-directory-wp.com/Technical_details/Fixing_issues_related_to_Kerberos/Unsupported_encryption_types_between_Samba_and_Active_Directory.html
https://lists.fedorahosted.org/archives/list/freeipa-users at
lists.fedorahosted.org/thread/FITCJOXX2QQ4HEXEK4PDJWFZJ2C33FAZ/
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/integrating_rhel_systems_directly_with_windows_active_directory/index
Maybe I will report this problem to Fedora's bugzilla.
