could it be a PAM issue? or what else? I am not even asked about 
credential, telnet refuses authentication before asking my credentials 
(thus it is nto a problem of e.g. root login.)

My PAM setup is untouched and looks like this for telnet:

# auth
auth            required        pam_nologin.so          no_warn
auth            include         system

# account
account         include         login

# session
session         include         login

# password
password        include         login
