Re: Migrating from Sun DSEE & Boolean values question

We're planning to migrate to OpenLDAP from Sun Directory Server. So far
the test setup works fine, with one potential problem. Sun's directory
server treats boolean values as case-insensitive, while the RFC (and
OpenLDAP) require upper-case TRUE and FALSE values.
Is there a way of forcing case insensitivity on boolean values with
OpenLDAP, so that any clients who are applying filters like "(foo=true)"
will continue to work? Or is the only way to maintain stats logging and
try to locate particular scripts on the machines that connect, and fix
each one in turn? I realise the former option is not RFC compliant, but
for me, it'll be very convenient to be permissive.
In the past I had to do what you're asking for; my customer even asked
me to support the use of 0/1 instead of TRUE/FALSE. It can be done with
few lines of portable code (I mean: without the need to patch the source
at each upgrade) by writing a module that replaces the validation &
normalization functions of the boolean syntax and equality matching
rule. This makes your own slapd tolerant with respect to syntax
violations. Please do not ask to provide this feature neither as a
modificaton to OpenLDAP code nor as a module, because this would make
incorrect values the de-facto standard, and nobody wants this. Fixing
the clients is the right approach.
