[SOLVED] Cacti 0.8.7a on Windows - LDAP Authentication

[Steve Ollis]

Hi,

We're running Cacti/Spine on a W2K3 server. I'd love to setup LDAP/AD authentication for Cacti, but the option isn't available in the Configuration->Settings->Authentication->Authentication Method drop down.. Only Builtin and WebBasic Authentication.

Ldap is loaded as a module in php.in, and confirmed by..

D:\webroot\cacti\scripts>php -m

so, any suggestions?

When you go to the technical support page, you see LDAP in there right?

[Steve Ollis]

Ah ha. No.. LDAP is not listed in there. So, what I need to do from here?

[BSOD2600]

Did you restart IIS after enabling ldap in php.ini? If not, do so.

[Steve Ollis]

Hi,

i've restarted iis, and the whole server several times.. since install and subsequent .ini file updates..

I'm guessing that means you still don't see ldap listed in the technical support page?

Create a file called info.php and put in the following:

Code: Select all

<?php
// Show all information, defaults to INFO_ALL
phpinfo();
?> 

Navigate to that page in IIS -- do you see LDAP listed? If not, then I don't think you've modified the correct php.ini file. Search your system for other copies.

[Steve Ollis]

There's only one php.ini file on the server.. and that's in c:\php\php.ini.

Output of phpinfo() is attached.. as is PHP.ini

Ok.. curiouser and curiouser - i set error logging up to ALL and output to syslog, and got the following at IIS restart time in event log..
Warning: PHP Startup: Unable to load dynamic library 'c:\php\ext\php_ldap.dll' - The operating system cannot run Warning

I didn't have openssl loaded, but that hasn't fixed it..

[Steve Ollis]

Ah! Fixed..

needed to copy ext/php_ldap.dll, libeay.dll and ssleay32.dll to my windows\system32 folder. Now Ldap shows up in PHPINFO().. now off to configure Cacti.

[BSOD2600]

Interesting. IIRC, those files should already live in the c:\php\ directory. If you had set the PHPRC system variable to c:\php, I believe you wouldn't have that problem. Basically it's a path issue.

I'm using php 5.2.x on Windows 2003 and did not have to move any files outside of the PHP folder to get LDAP working.

[Steve Ollis]

phprc IS set to c:/php. you can see that in the phpinfo output...

and those files, except for php_ldap.dll, were in c:/php.

very curious indeed...

[BSOD2600]

Hmm, ok. Well while this might work now, it WILL cause problems in the future when you upgrade PHP because I bet you'll forget about those other dll files in the windows\system32 folder.
