If you can reproduce that, I'd suggest filing an ITS at:


Would you say that's a bug? Just to clarify, I mean I split out my access controls into master.acl and have a line

include /usr/local/etc/openldap/masta.acl

in slapd.conf, but masta.acl itself has a line saying

include /usr/local/etc/openldap/masta.acl

at the top.

I call that pilot error - though I'll still file an ITS if you like...

It certainly is a pilot error, but the error you are reporting it saying is really non-intuitive to the problem. I would hope that the parser would throw a meaningful error if the same file is included twice, rather than 'Too many open files'.

fantasy and sf books, which foster that deadly enemy to bigotry and blind
faith, the imagination." -- Ursula K. Le Guin
