memberof overlay surpresses accesslog olcAccessLogOps = all

Hi All,

I would appreciate it if someone could give me some insight into the following issue:

I have a standalone openldap 2.4.26 setup. We would like to use the accesslog overlay for auditing. I have enabled the accesslog overlay with olcAccessLogOps = all. This writes all groups of operations (writes, reads, session) to cn=accesslog without issues. We would also like to make use of the memberof overlay. The issue we're seeing is that once you enable the memberof overlay, only search, unbind, add operations are logged to accesslog. We do not see delete, modify, modrdn values logged. If I then change the logops to "olcAccessLogOps = add delete modify modrdn" we see those operations logged, but no bind, search, unbind operations (ie. no reads or session).

Is this a limitation of using these two overlay's together, or am I completely missing something?

Here is the configuration output:
