RE: [Fedora-directory-users] Account lockout counters not replicating; how to unlock users?
Hmm; thanks very much for your help; so what are my options? Changing from supplier/consumer to multi-master? Does the global password issue still exist in a multi-master environment? Are there any concerns with this? Or is the global password issue with supplier/consumer replication something that is or can be addressed? Thanks.

Yes, this is a limitation of password policy. What you really want is for the consumer to pass the BIND request back to a master and have all of the password policy attributes computed on the master to be replicated to all other servers. Ulf, were you ever able to get Chain On Update to work in this configuration? http://directory.fedora.redhat.com/wiki/Howto:ChainOnUpdate
I think using the passthrough plugin to pass the bind back to a central point was the only solution I came up with but it needs a patch, it doesn't like getting controls back (Bugzilla #176302).
For ChainOnUpdate I didn't see a way to get it to work for this case.
The internal update that adds the PWP state didn't seem to get chained, only updates coming from external clients.
Oh, that's right. We need to chain the bind requests.
So the answer to the original question is - no - you cannot have global password policy yet.

Hello Aaron. Two separate things: I may have misunderstood your configuration, but nothing is replicated from a consumer to a master unless the consumer is actually configured as a hub with an agreement back to the supplier.
You can use passthrough authentication trickery to cause binds to be
performed at the master if you don't want bi-directional
replication.
Also, those three attributes (passwordRetryCount, retryCountResetTime, accountUnlockTime) are special and will not replicate in any case unless you set passwordIsGlobalPolicy to on in cn=config.

Subject: [Fedora-directory-users] Account lockout counters not replicating;how to unlock users?
Here's my setup; 2 directory servers, 1 supplier, 1 consumer; I'm not sure why, but for some reason I'm not seeing password retry counters being replicated from the consumer to the supplier; here is what I've seen (I have fds setup to lock accounts after 5 bad password attempts, reset failure count after 15 minutes): -if a user types their password incorrectly on a server that binds first to a consumer, then their password retry count increments only on
the consumer -if a user successfully binds to the server, then their password retry count does get reset This is a problem for a couple of reasons. If an account becomes locked out because of bad password attempts, I've tried deleting the attributes of passwordRetryCount and accountUnlockTime (http://directory.fedora.redhat.com/wiki/Howto:PasswordReset) from the supplier, however for some reason this is not replicated to the
consumer (is this an indication of a different problem?) this is a
problem as I have some of my linux servers to look to the supplier first for authentication, and then the consumer second, and visa versa for load balancing. According to fds documentation, account lockout counters may not work as expected in a multi master environment http://www.redhat.com/docs/manuals/dir-server/ag/7.1/password.html# 1086
4 46 ; this is one of the reasons that I opted for a single master environment; please advise and thanks. Given the issues that I'm having, what is the best way to unlock accounts that have been locked due to bad password attempts?

That would certainly solve the problem.

No.

AFAIK there is no other way to do it. We've got a couple of ways to do it that we're working on.
Thanks.
