I admit attribuet mapping has been sometime unclear in its usage, 
however I never noticed such problems in its usage.  Of course
I didn't use it intensively, only played with it for a while.

Can you clarify the point further, before I commit your patches?
I also note that the patch does not apply cleanly to HEAD code
(possibly due to Howard's recent commits, or mine) and fails
for very simple cases like 

database ldap
uri             "ldap://localhost:9009/";
suffix          "dc=umich,dc=edu"
suffixMassage   "dc=umich,dc=edu" "o=University of Michigan,c=US"
map attribute ou

added to the slapd.conf resulting from test003 results in a sigsegv :)

Good catch :=)
