So I rebuild all and when I start wbinfo -u
I got this messages :

Got winbind samba3 request 0
Got winbind samba3 request 45
Got winbind samba3 request 17
wbsrv_samba3_list_users called
wb_cmd_list_users_send called

added interface ip= nmask=
added interface ip= nmask=
added interface ip= nmask=
sys_gethostbyname: Unknown host. TST

Where TST is the domain name and my realm is smb4.tst.
