Sounds odd; can you provide a log at level "packets" of the request with php? I suspect it's doing something like

dn: uid=user,ou=people,dc=example changetype: modify replace: autoreply

This was the problem, it was ignoring Replace when no values were provided. Fixed now in HEAD and RE23.

or

dn: uid=user,ou=people,dc=example changetype: modify delete: autoreply autoreply: TRUE

which, although semantically equivalent to what you tried, could be handled differently by acesslog(and that would be a bug)
