any script containing the following function will produce the error:

ldap_get_values_len

which is a "call to undefined function"  But all of the other LDAP functions work.  The PHP manual says this function exists, but doesn't seem to in real life.  My configure line is as follows:

./configure   --enable-track-vars \
    --with-apxs=/www/bin/apxs \
    --with-ftp \
    --with-imap \
    --with-ldap \
    --with-mysql \
    --with-mm \
    --with-sysvsem \
    --with-sysvshm \
    --enable-wddx \
    --enable-xml \
    --with-gettext \

I don't think the php.ini file is relevant, but if you need it, please e-mail it to me and I will send it to you.
