What i can do???
there`s a way more simple with SAMBA??
I try
-------------------------------------------------------
Join host to domain with net ads join
Create keytab for HTTP/fqdn with net ads keytab
kinit administrator at DOMAIN
export KRB5_KTNAME=FILE:/etc/squid/HTTP.keytab
net ads keytab CREATE
net ads keytab ADD HTTP
unset KRB5_KTNAME
------------------------------------------------------------
And i get
[root at squid squid]# export KRB5_KTNAME=FILE:/etc/squid/HTTP.keytab
[root at squid squid]# net ads keytab CREATE
[root at squid squid]# net ads keytab ADD HTTP
Processing principals to add...
../source3/libads/kerberos_keytab.c:331: unable to determine machine
account's dns name in AD!
Some help???
Thanks!
