Hi there,
I think I found a bug.
I detected that my (compiled from source) openldap crashes on node rename. I run gdb and detected an infinite (too big) recursion that seems to be related with the "memberof" overlay.
I'm not familiar with openldap sources, so I decided to post it here, and then try to help fixing it with your advice:
This is the GDB / debug output:

Any idea of why could this be happening?
