Bug #16005 Updated: Conflict between OpenLDAP and Oracle

ID: 16005 Updated by: fmajid@kefta.com Reported By: fmajid@kefta.com Status: Open Bug Type: LDAP related Operating System: Solaris 8/Intel PHP Version: 4.1.2 New Comment: This does indeed fix the ldap_modify_s problem, at least with 4.2.1, although libphp4.so is still linked with the Solaris standard /usr/lib/liblber.so. Previous Comments: ------------------------------------------------------------------------ [2002-06-21 15:45:16] venaas@php.net Since you got Oracle with LDAP support, you could also use that instead of OpenLDAP. To use Oracle for LDAP you write something like --with-ldap=/usr/local/oracle/product/8.1.6 ------------------------------------------------------------------------ [2002-03-11 16:27:58] fmajid@kefta.com PHP dumps core when compiled with both LDAP and OCI8. The reason is the Oracle client libraries include an LDAP library, and PHP is calling the Oracle ldap_modify_s instead of the OpenLDAP ldap_modify_s. We are using OpenLDAP 1.2.11 and Oracle 8.1.6. Short-term workaround: use LD_PRELOAD, e.g. add: LD_PRELOAD=/usr/local/ldap/lib/libldap.so export LD_PRELOAD to your Apache start scripts.
