Re: Multiple Server Controls

I don't recall there being any technical specification detailing
how these two controls may be used together, so there is no general
answer to your question (except don't mix controls where there is
no technical specification detailing how they may be used together).
The slapd(8) specific answer is that the DirSync control will be
ignored unless critical as its not implemented.  Use LDAPsync
instead (without combining it with the paged results controls).
