Nothing related to this except the search result errors.
I tinkered with the limits and got a search to give me returns. I made them massively large (100k). I’ll work on tuning it down, but that looks like it was it. Thanks for the help Rich!
What I can’t reconcile is that we have the same limits on the master directories, but those don’t have issues. They must not be receiving anonymous searches on these DNs, or even non-anonymous SEARCHES on them
I guess. They get written to and replicate from them just fine though – I need to understand LDAP better
J.
Now just on to the replication conflict issue, but I do have a ticket with redhat open for that.

Thanks for those answers Rich - I forgot to change the subject line from the naming conflict issue mail I sent!
I will try bumping the limits some and hitting some immediate ldap searches.
It seemed to me that it went from err=11 to err=53 once I tried the anonlimitsdn change. But I reverted that, and it stayed with err=53.
Any errors in the errors log?
Replications were ongoing, but at that time I made no other config changes.

Hi All –
I’ve got another one today.
We have 1 attribute in our infrastructure that’s extremely large – it’s a PKI CRL that’s around 15MB. It sits in an entry that has about 6300 sub entries.
That shouldn't necessarily be a problem. We have customers with 100MB CRL entries.
We had some previously mentioned issues running out of file descriptors on our consumers.
That's usually a matter of tuning.
After resolving those, we were getting err=11s on searches under that entry, returning nentries=699,700,701. 700 didn’t make sense, but I thought that the issue might be the search limit – these are anonymous,
so I tried the anonlimitsdn setting with a template, and set it higher than 700. That wasn’t it.
err=11 is usually related to either 1) look through limit 2) nsslapd-idlistscanlimit 3) unindexed searches.
We then started getting err=53s searching that entry – we don’t even seem to get the err=11s anymore.
What changed? Something must have changed. Or are you saying that for no reason, the exact same search under the exact same circumstances began returning a different result?
These searches ARE showing up un-indexed. We have indexes for the attributes though
The indexes are related to the search filter:
filter="(&(|(objectClass=cRLDistributionPoint)(objectClass=pkiCA))(cn=CRL*8))"
In this case, the objectclass equality index, and the cn substring indexes. Both of these are indexed by default.
So it is likely due to nsslapd-idlistscanlimit being set too low for this search.
https://access.redhat.com/site/documentation/en-US/Red_Hat_Directory_Server/9.0/html/Administration_Guide/Managing_Indexes.html#About_Indexes-Overview_of_the_Searching_Algorithm
The nsslapd-idlistscanlimit is "the configured ID list scan limit".
– is it because of the ;binary versions?
Definitely not.
