I would like to clarify myself, i wasn't accurate when i compared it to : https://bugzilla.redhat.com/show_bug.cgi?id=878564.
I have tried to reproduce the bug by restarting the AD. *I was able to preform winbindd commands:* [root@ipaserver1 ~]# wbinfo -u ADEXAMPLE\administrator ADEXAMPLE\guest ADEXAMPLE\genadi ADEXAMPLE\krbtgt ADEXAMPLE\linux$ ADEXAMPLE\daniel [root@ipaserver1 ~]# wbinfo -g admins editors default smb group ad_users ADEXAMPLE\domain computers ADEXAMPLE\domain controllers ADEXAMPLE\schema admins ADEXAMPLE\enterprise admins ADEXAMPLE\domain admins ADEXAMPLE\domain users ADEXAMPLE\domain guests ADEXAMPLE\group policy creator owners ADEXAMPLE\read-only domain controllers ADEXAMPLE\enterprise read-only domain controllers ADEXAMPLE\dnsupdateproxy [root@ipaserver1 ~]# wbinfo -n "ADEXAMPLE\administrator" S-1-5-21-2887728911-2909484380-3974070232-500 SID_USER (1) [root@ipaserver1 ~]# wbinfo -n "ADEXAMPLE\guest" S-1-5-21-2887728911-2909484380-3974070232-501 SID_USER (1) [root@ipaserver1 ~]# wbinfo -n "ADEXAMPLE\genadi" S-1-5-21-2887728911-2909484380-3974070232-1000 SID_USER (1) [root@ipaserver1 ~]# wbinfo -n "ADEXAMPLE\krbtgt" S-1-5-21-2887728911-2909484380-3974070232-502 SID_USER (1) [root@ipaserver1 ~]# wbinfo -n "ADEXAMPLE\linux$" S-1-5-21-2887728911-2909484380-3974070232-1104 SID_USER (1) [root@ipaserver1 ~]# wbinfo -n "ADEXAMPLE\daniel" S-1-5-21-2887728911-2909484380-3974070232-1105 SID_USER (1) *But kinit with AD users failed:* [root@ipaserver1 ~]# kinit gen...@adexample.com kinit: Cannot resolve servers for KDC in realm "ADEXAMPLE.COM" while getting initial credentials *But after few minutes i was able to to kinit with AD users agian:* [root@ipaserver1 ~]# kinit gen...@adexample.com Password for gen...@adexample.com: I think i was too fast on making conclusions.
