Helo list, I have samba 4 betta5 as BDC, when I run ./samba-tool dbcheck:

Failed to correct missing instanceType on
DC=81db8c7b-70f3-4bb0-941f-a9b3abb69b04._msdcs\0ADEL:6334f796-af60-4238-8e5a-1610056ca9b6,CN=LostAndFound,DC=eccmg,DC=cupet,DC=cu
by setting instanceType=4 : (65, "objectclass_attrs: at least one
mandatory attribute ('objectCategory') on entry

wasn't specified!")

I can see in active directory users and computers the folder lost and
found, how I can delete all record in this place... I run too ./samba-tool
dbcheck --fix and nothing happened.
