SASL Bind vs. PHP Bind

["Herbert G. Fischer" <hgfischer@trama.com>]

Hi again,

I'm using Postfix+SASL+OpenLDAP to do SMTPd autentication for users,
and it's working very well.

But, I'm creating a small system with PHP that must authenticate on
LDAP too (using ldap_bind). But it's not working and I don't have idea
why, since my log messages doesn't show me nothing important.

I know that there is a lot of difference on them, but it not seems logic to
me. Can anyone explain me what I need to auth someone via lda_bind??

Thanks,
