I expect the errors are rather benign... Like: Jul 27 08:19:37 eldaph22 ns-slapd: [27/Jul/2020:08:19:37.743355076 -0700] - WARN - NSACLPlugin - acl_parse - The ACL target cn=blah,dc=ubc,dc=ca does not exist
"Fix" was to either create cn=blah,dc=ubc,dc=ca or delete the ACI. Thank you for the instructions on how to turn on ACI logging. I've stashed them for when we might need them. 😊 Cheers, Anthony -----Original Message----- From: Mark Reynolds <[email protected]> Sent: July 28, 2020 10:48 AM To: General discussion list for the 389 Directory server project. <[email protected]>; Winstanley, Anthony <[email protected]> Subject: Re: [389-users] Re: Limitations with large numbers of ACIs?

First, there is an ACI cache that could be corrupted, which explains why a restart fixes the issue. Second, you are saying you "cleaned" some things up. What exactly did you do? And what were the exact errors messages you saw that led you to the "clean up"? If the ACI's start failing again then there is a good chance you found a bug in the ACL cache. What would be interesting to see would be the error log with ACI logging enabled [1], where you have the output when it works, and then you have the output once it starts failing. Then we would have something to compare. With so many aci's this is going to be tedious, but it might be the only option besides identifying a reproducible test case.
