[Fedora-directory-users] lookthrough vs. sizelimit

[George Holbert]

Something I've been wondering about:
It seems like nsslapd-lookthroughlimit and nsslapd-sizelimit effectively 
do the same thing, but just return a different error code.

If nsslapd-lookthroughlimit is lower, the error code is 11 and the error 
message is:
ldap_search: Administrative limit exceeded

If nsslapd-sizelimit is lower, the error code is 4 and the error message is:
ldap_search: Sizelimit exceeded

I've read the description of both of these variables many times in the 
documentation, and I think I understand the theoretical difference.  But 
in practical terms, it still seems like whichever has the higher value 
will never have an effect, since the lower limit on the other is always 
hit first.

Can anyone describe a practical situation where both the lookthrough and 
size limits would come into play?
Is there any particular reason to prefer one or the other to enforce 
maximum search result limits?


Thank you!
