When combining server roles to perform many tasks with one server there is a lot of potential for things to trip over themselves.<\/p>\n
This started as a simple ‘Provide an LDAP connection between SugarCRM and Active Directory’.<\/p>\n
Issue: Configuring the LDAP settings for SugarCRM is relatively easy but when trying to test by setting a specific user to ‘Use only LDAP Authentication’ the SugarCRM login page reports that the LDAP extensions are not loaded. Ok, so its a PHP config issue.<\/p>\n
Issue: The PHP error log shows that not only is LDAP an issue but also CURL and a few other PHP extensions are not loading. With a ‘File not found’ error.<\/p>\n
The extension files are all there, the paths are correct, etc. The issue appears to be that some supporting files are missing including libeay32.dll and ssleay.dll, so preparing a fresh install of PHP with these options enabled adds the files to the PHP directory. But the error persists.<\/p>\n
Issue: PHP 32 bit not 64 bit so we need to set the Application Pool to allow for 32 bit applications. But this triggered another series of issues.<\/p>\n
Issue: Attempting to set 32 bit for any App Pool on the server crashes with errors.
\nThe browser returns an error 500 Internal Server Error.<\/p>\n

The Module DLL ‘C:Program FilesMicrosoftExchange ServerV14Binkerbauth.dll’ could not be loaded due to a configuration problem. The current configuration only supports loading images built for a x86 processor architecture. The data field contains the error number.

Which\u00a0led me to Chris’s Blog and issues with setting 32 bit apps on an OWA server<\/a>. Following those instructions which can be summarised as follows:<\/p>\n
\n
- Stop the IIS Service<\/li>\n
- Edit C:WindowsSystem32inetsrvconfigapplicationHost.config<\/li>\n
- Edit the following 3 lines to append\/insert the preCondition=”bitness64″ option<\/li>\n
- <add name=”kerbauth” image=”C:Program FilesMicrosoftExchange ServerV14Binkerbauth.dll” preCondition=”bitness64″ \/><\/li>\n
- <filter name=”Exchange OWA Cookie Authentication ISAPI Filter” path=”C:Program FilesMicrosoftExchange ServerV14ClientAccessowaauthowaauth.dll” enabled=”true” preCondition=”bitness64″\u00a0\/><\/li>\n
- <filter name=”Exchange ActiveSync ISAPI Filter” path=”C:Program FilesMicrosoftExchange ServerV14ClientAccesssyncbinAirFilter.dll” enabled=”true” preCondition=”bitness64″ \/><\/li>\n<\/ul>\n
- Start the IIS Service<\/li>\n
- Set an Application Pool to use 32 bit Applications<\/li>\n
This resolved the 32 vs 64 bit war and brought me back to the PHP issues that started this.<\/p>\n
Issue: Curl and other extensions not loading. <\/p>\n
So I tried running php from the command line<\/p>\n
\nD:Applicationsphp> C:progra~1phpphp-cgi.exe
\nPHP Warning: PHP Startup: bz2: Unable to initialize module
\nModule compiled with module API=20060613, debug=0, thread-safety=0
\nPHP compiled with module API=20060613, debug=0, thread-safety=1
\nThese options need to match
\n in Unknown on line 0
\nPHP Warning: PHP Startup: Unable to load dynamic library ‘C:Program Files (x86
\n)PHPextphp_curl.dll’ – The specified module could not be found.
\n in Unknown on line 0
\nPHP Warning: PHP Startup: dba: Unable to initialize module

\nPHP compiled with module API=20060613, debug=0, thread-safety=1
\nThese options need to match
\n in Unknown on line 0\n<\/p><\/blockquote>\nSo this suggests that it is not a missing file or path but the thread-safety option which is weird as everything I have read including the name of the download is ” PHP Non-Thread Safe” so why would the installer be installing a modules compiled differently to the PHP install? I will probably never know. I gave up at this point and removed PHP 5.2.8 completely and installed 5.3.8 via the Microsoft Installer<\/a> for PHP which enabled curl and ldap but led to a whole different world of pain.<\/p>\n","protected":false},"excerpt":{"rendered":"
