How to modify the attribute nsslapd-encryptionalgorithm in Centos?
Stop Master servers and set nsslapd-encryptionalgorithm. The allowed value is AES or 3DES.

As far as replication goes - you will need to use a security layer
(SSL, TLS, or GSSAPI) to protect the clear text password on the wire
As far as encrypting it in the changelog - not sure

Description of problem:
When a userPassword is changed in a server with changelog, the hashed password
is logged and also a cleartext pseudo-attribute version. It looks like this:
This unhashed version is used in winsync where the cleartext version of the
password must be written to the AD.
Now if the DS is involved in replication with another DS, the change will be
replayed exactly as it is logged to the other DS replicas, including the
cleartext pseudo-attribute password.
What platform? What version of 389-ds-base are you
389 users mailing list
We have a master - master replication agreement. When we initialize the replication it works perfectly we can see changes to a test user we have set up go up and down from the two servers. However at some point the replication stops and we cannot get replication to start once again. The only way we can get replication to start once again is to recreate the replication agreement and then it fails again. Can anyone please point us in a direction. I am relatively new to 389 so any help would be greatly appreciated.

During the bind process is there anyway to tell 389 directory server to
hash a plaintext password n (multiple) times before trying to compare to
what is stored?
I am trying to implement something similar to what's described in this
Our plan was to to use SSHA256 to hash the passwords around 200,000 times
before storing. This would at least slow down any cracking attempts should
someone get access to our directory.
I've read through the documentation on the Red Hat Directory Server site,
including the "Plug-in Guide". Under "5.8 Checking Passwords" it refers to
calling function "slapi_pw_find_sv()" - looking at the doc for this
function it does not look like hashing multiple times is supported.
Is there some means of doing this that is not obvious to me?
I can certainly do it by re-writing the security plugins for the various
servers (Tomcat, PHP Wordpress, etc) such that they hash the plaintext
password n minus 1 times before issuing the bind - but was hoping not to do
I'm relatively new to 389 directory server, but so far quite happy to have
moved to it from another directory server.
Thank you - Richard

We are trying to reindex RHDS 9.1 after importing an updated index. Services were stopped. Started the /usr/lib64/dirsrv/slapd-instance/db2index.
Reindex starts but then consistently reports:
Processed 300,000 entries ( pass 1)
Processed 300,000 entries ( pass 2)
and keeps repeating that sequence with same amount of entries. How long does it usually take to complete the process and is there a limit or issue with this feature? This happened once before and system was left overnight performing indexing only to still processing with new passes. We ended up breaking the process and just reinitializing the server.

In setting up my 389-ds instance for SSL, the dirsrv instance doesn’t appear to recognize cert9.db or key4.db, the SQLite NSS database formats. Did I miss a setting? Is 389-ds restricted to cert8.db/key3.db? A quick search of the 389-ds wiki didn’t help; Google returns a lot of noise and not much signal.

I need to be able to reset a LDAP user's password if they forget it with the user root. But when I try the "passwd" command as root for a LDAP user, I get the following:
Changing password for user tuser.
Password reset by root is not supported.
passwd: Authentication token manipulation error.
I am using sssd as the LDAP authentication mechanism tool, to be specific. Does anyone have a solution to dealing with this issue of resetting a LDAP user's password if they forgot it?

Subject: using passwd with 389
I want to be able to use the Unix "passwd" command to reset a LDAP user's password from the command line. However, I keep getting an authentication token manipulation error whenever I try to reset the password using that command. What do I need to do in the 389 DS or on Unix in order to get this command to work?
Hi All -
We had a bundle of problems with our MM/consumer setup. Ran of out FDs on the consumers, had the slapd process on a master die, etc.
We're getting things back up and running properly, but having some replication issues now. We've got it mostly cleaned up - the masters are in sync, and all consumers but 1 hub.
However, 1 hub has 3 naming conflicts on an entry. How can we resolve these? Since it's read-only, the normal documented processes won't work of course. The non-conflicted entry isn't receiving updates from the masters. We use the directory for PKI, and the entry contains a CRL that is going to expire - not good.
Do we need to just wait, and the actual entry will get updated at some point? With the errors we had, it seemed to take a long time for the directories to replicate around and catch up.
