Re: [PHP-DEV] Bug #3613: ldap_mod_replace does not handle binary values properly From: Andi Gutmans (andi <email protected>)
Date: 02/24/00

 From looking at the ldap.c source code and not having written the ldap
module myself it does seem that ldap_modify does not handle binary data. I
am including a small paragraph from the ldap_modify man page at the end of
this letter which gives a short pointer on what to do with binary data.
Parts of the LDAP module actually do seem to work this way so maybe you
need to use a different function. I'm Cc'ing the authors of the LDAP
module. They might be able to enlighten us on this issue.

 From the OpenLDAP ldap_modify man page: 

---
  If you need to specify a non-string value (e.g., to add a photo or audio 
attribute value), you should set mod_op to the logical OR of the operation 
as above (e.g., LDAP_MOD_REPLACE) and the 
constant  LDAP_MOD_BVALUES.   In  this case, mod_bvalues should be used 
instead of mod_values, and it should point to a null-terminated array of 
struct bervals, as defined in <lber.h>.
