[PHP-DEV] things I don't like with ldap_search() From: Stig Venaas (Stig.Venaas <email protected>)

There a few things that I don't like with the current ldap_search().

There are several situations where there are data returned from a search
where the result is not LDAP_SUCCESS, current code will return the data
if the result is LDAP_SIZELIMIT_EXCEEDED, but I would also like to do it
when the result is LDAP_ADMINLIMIT_EXCEEDED and probably others.

With LDAPv3 there are also situations where you get a referral or other
errors where you need the result entry to see what happened. I'm writing
a function to extract this from the result, but then I need ldap_search()
to return a result identifier also for LDAP_REFERRAL and some others.

So, I want ldap_search() to return a result identifier more often than
it currently does, personally I would like it to always return a result
identifier unless ldap_search_s() returns -1. Then PHP applications can
always get all the information about what happened, and get all error
messages, result codes, referrals etc. from the results.

The problem with this, is that there might be applications that think
that there were no matches, when the reality is that something went
wrong. They could use ldap_errno etc. to see what happened but there
are probably a lot of poorly written PHP scripts that don't bother.
These scripts don't work that well today either though, there might
be some data returned from the server, while they just think that the
search didn't work, or with sizelimit exceeded they believe they got
all the data (there is a PHP ERROR given though).

Bottom line: Can I change ldap_search() to more often return an
             identifier to get some new possibilities even though
             some scripts will think everything was okay and that
             there were no hits? There are alternatives like adding
             a 9th (too many) parameter or an alternate function, I
             don't like them.

Hope I managed to make myself clear, I'll be happy to discuss this
further. Comments?
