Hello all,
we are currently facing issue with huge number of outdated certificate entries in o=ipaca LDAP subtree (many servers no longer exists, certificates already expired etc) and we would like to remove them to decrease number of entries in LDAP and also to speed-up initial replication of o=ipaca subtree (we have more than 700 000 DNs in o=ipaca and deploy of new replica takes quite long).
Does anyone tried to do something like this? I'm quite affraid if simple ldapdelete of many DNs in o=ipaca subtree wouldn't break DogTag somehow.
Do you have any ideas if something can break by removal of old (expired and also non-expired) certificates from o=ipaca ? Thanks in advance for any advice.

It is not a supported operation, but I cannot think of any problems that would arise from removing the certificate records under o=ipaca. But I am copying pki-users@ to get the attention of the rest of the Dogtag team in case there is something I am not thinking of. Strictly speaking, you should only remove expired certificates, even if a host has disappeared the validity period is a promise by a CA to maintain knowledge about a certificate for that whole period. (Note to Dogtag team: FreeIPA configures Dogtag to use sequential serial numbers. The usual range mechanism applies for CA clones). HTH, Fraser
I agree with what Fraser says. Non-expired certs (revoked or not) should never be removed from the CA repository as that will affect the CRL I believe someone asked about this before, and we also warned them about that. Though I have no recollection how it worked out for them in the end. You could do a backup before you try. regards, Christina On 07/30/2017 10:14 PM, Fraser Tweedale wrote:
