I want to connect to Windows Active Directory from CentOS 7 with Samba, winbind.
Samba is already running but Winbind is not errored by following error at log.winbindd.

../source3/winbindd/winbindd_util.c:891(init_domain_list)

Could not fetch our SID - did we join?

I try "net -d 10 ads join -S dcserver -U poweruser" then get error log.
what parameter is Invalid? what parameter ddidn't I write in my config?
I don't know "dn" written in this log.

kerberos_kinit_password: as poweruser@DMNAME.OURCO.JP using [MEMORY:libnet_join_user_creds] as ccache and config [/var/lib/samba/lock/smb_krb5/krb5.conf.DMNAME]

return code = -1

msg_dgm_ref_destructor: refs=(nil)

I resolved by myself.
I didn't know but "dcserver" was alias of "dcserver-1" in Active Directory.
So It works after I replace it "dcserver-1" - net ads join -S dcserver-1 -U poweruser!

I guess maybe "dcserver-1" is specified in ldap config, but because I have no right of Active Directory Administration, so I'm not sure.

Thanks.
