Bug #14355: ldap_connect works intermittantly

From: liamr@umich.edu Operating system: Solaris 2.6 (SPARC) PHP version: 4.0.6 PHP Bug Type: LDAP related Bug description: ldap_connect works intermittantly server config - Sun Ultra 2 (dual 300mhz IIs), 768MB RAM, Solaris 2.6 (SPARC), Apache 1.3.20, PHP 4.0.6 (and 4.0CVS- 12-0-4) configured as DSOs. I'm trying to build PHP as an apache module w/ support for LDAP (for use w/ HORDE). PHP builds fine, and apxs is able to make the .so file, but I regularly get "Unable to connect to LDAP server". Apache doesn't segfault, and phpinfo() shows that LDAP support has been built in. There is no mention of it in my php error log, nor my apache error log. My build was fairly complex (including support Oracie 8i, which I disabled when I found the OpenLDAP / OCI8 / Solaris threads in the bugs database). I've tried building against OpenLDAP 1.2.12, 1.2.13, 2.0.18 and the Oracle LDAP library that ships w/ 8.1.17 (when I added --with-oci8). The most basic configuration line looks like: env CC="gcc" \ CFLAGS="-I/usr/local/openldap/include" \ CPPFLAGS="-I/usr/local/openldap/include" \ CXXFLAGS="-I/usr/local/openldap/include" \ ./configure --with-apxs=/usr/local/apache/bin/apxs \ --with-ldap=/usr/local/openldap I make distclean between re-configure and re-builds. I've tried gcc 2.95.2, 2.95.3, and the Sun Workshop (4.2) version cc. I've had no problem with PHP+LDAP when built as the CGI. The DSO has been very flakey. I've not tried building PHP directly into Apache. If the DSO works, it works until the apache is restarted. I've not kept track, but I'd say at least 75% of the time after apache is restarted (or stopped and started), LDAP doesn't work - and this behavior is consistant with the various LDAP libraries I've tried. I wish I could provide more information - is there additional debugging I can turn on, or maybe add to the C code? thanks much -- Edit bug report at: http://bugs.php.net/?id=14355&edit=1
