I believe that 4  uses of strcasecmp in servers/slapd/acl.c are in 
error and use the reverse logic to that intended. 

Namely, strcasecmp returns a 0 on a string match (case insensitive)
but the logic in parts of acl.c suggest that the original author
assumed a return value of 1 on string match. This is during
the acl <who> clause evaluation.

I've included a patch that reverses this logic to that
probably intended. I posted to openldap-devel to confirm
that it was a bug.
