[Samba] Orphan SPN

I think I got orphan SPN in KDC. I want to remove it, but I cant find 
user of that SPN.

That is why I think it is actually an orphan SPN:

#samba-tool domain exportkeytab orphan.keytab --principal=cifs/oml.su

Output gives me keys.

But then, also this works:

#samba-tool spn add cifs/oml.su oljas

#samba-tool spn delete cifs/oml.su oljas

And then, this still works:

#samba-tool domain exportkeytab orphan.keytab --principal=cifs/oml.su

I`ve tried to search SPN via ldapsearch, powershell and in ADUC going on 
objects one by one. Cant track it.

I think, that this SPN was created by me years ago for some 
insignificant reason. But I cannot recall how I did it. Since then DFL 
was reised from 2003 to 2008, if that matter.

Is there any way to find out which user holds that SPN, or is there any 
way to remove it?
