Hello,We have a linux machine with a hostname that is longer than 19 characters. AFAIK the SamAccountName attribute in AD is limited to at most 20 characters (inkl. trailing $). I.e. the usable characters is at most 19.
In many AD docs it is stated that a Windows hostname should not exceed 15 characters for backward compatibility, but we do not really care about that.
Could you comment on how does SSSD pick the principal / username name to use for kerberos / ldap authentication / reading the keytab / and so on in the case of the hostname being longer than 19 characters?
I could not find anything in the docs of sssd-ad about this. Will it use 1) UNRESTRICTED_VERY_LONG_HOSTNAME$ 2) 19_CHARACTERS_HOSTNAME$ 3) 15_CHAR_HOSTNAME$ ?Thanks for clarifying. It will help us deciding on how to proceed with hosts with long host names.
Best regards, J Brauchle
