ID: 42642 User updated by: roberto dot valsania at mail dot wind dot it Reported By: roberto dot valsania at mail dot wind dot it -Status: Feedback +Status: Open Bug Type: Sybase (dblib) related Operating System: FEDORA CORE 7 PHP Version: 5CVS-2007-09-12 (snap) New Comment:
As i wrote i have the same sybase libs ( with ldap resolution) but the old PHP 5.1.6 ( on FEDORA CORE 5) and it works. I could try to compile this PHP with the FEDORA CORE 5 ( and the old openldap libs ) and see what happen Previous Comments: ------------------------------------------------------------------------ [2007-09-12 11:05:23] [EMAIL PROTECTED] Did you have same sybase libs in the other system too? It seems to me that there's simply a conflict between openldap and sybase's own ldap implementation and there's not much we can do about that.. ------------------------------------------------------------------------ [2007-09-12 09:44:39] roberto dot valsania at mail dot wind dot it Note that to have ldap support sybase client shuld be 12.5.1 or 15. I made test with Sybase OpenClient 15 The same configuration ( enable ldap and sybase ) with php 5.1.6 and fedora core 5 works ------------------------------------------------------------------------ [2007-09-12 09:31:47] roberto dot valsania at mail dot wind dot it Description: ------------ PHP sybase_conect Crash when compiled with with-sybase and with-ldap and sybase name resolution is done via LDAP If PHP is compiled without ldap extension all works. If Sybase resolution is done via interface file and not via LDAP all works To reproduce : 1) Compile php with : ./configure --enable-debug --with-sybase=/sbrdbms/sybase/OpenClient15/OCS-15_0/ --with-ldap Enable ldap sybase resolution by uncomment the following line in $SYBASE/$SYBASE_OCS/config/libctl.cfg ldap=libdldap.so ldap://ldaphost/dc=sybase,dc=com Please note that in this example the ldap server is only the default example. In this situation the sybase_connect should return error instead of a stack trace 2) Run the following simple php script <?php $my_server='DBA_SUN_TEST' ; $passwd='xxxxxx'; $login='sa'; $db=sybase_connect($my_server,$login, $passwd) ; sybase_close($db); ?> Reproduce code: --------------- To reproduce : 1) Compile php with : ./configure --enable-debug --with-sybase=/sbrdbms/sybase/OpenClient15/OCS-15_0/ --with-ldap Enable ldap sybase resolution by uncomment the following line in $SYBASE/$SYBASE_OCS/config/libctl.cfg ldap=libdldap.so ldap://ldaphost/dc=sybase,dc=com Please note that in this example the ldap server is only the default example. In this situation the sybase_connect should return error (because it don't find the ldap server correct configuration) instead of a stack trace 2) Run the following simple php script <?php $my_server='DBA_SUN_TEST' ; $passwd='xxxxxx'; $login='sa'; $db=sybase_connect($my_server,$login, $passwd) ; sybase_close($db); ?> Expected result: ---------------- an error or a sucessfull connection Actual result: -------------- A segmentation fault .
