"created the hashes"? There is nothing in https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Windows_Integration_Guide/Setting_up_Active_Directory.html#ad-ca-req about creating any hashes.
Sorry I should have been more specific. I mean updated the hash symlinks which is in 7.5.1 (7) here : https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Windows_Integration_Guide/managing-sync-agmt.html
