Using PHP with LDAP

[Thomas Berton <thomas.berton@ugent.be>]

Hello,
I'm having trouble using LDAP functionality within PHP. Running the PHP 
script from the command line works just fine, using the Apache user. 
However accessing the PHP script through HTTP does not give the same result.
I've narrowed down the problem to a certificate issue, in fact it is a 
self signed certificate so I've changed the ldap.conf file setting 
TLS_REQCERT to 'allow'. Also changing the permissions to make it 
readable for the Apache user. Those settings were necessary to run the 
script from the command line. However this does not seem sufficient to 
succesfully run the script from HTTP.

Also the .ldaprc file seems to be ignored. I've tried to place this file 
in the home dir of the Apache user with the setting mentioned above but 
no changes were visible when running the PHP script.

To be more precise about the PHP script: it tries to connect to the LDAP 
server using v3 with ldaps.

Apache does not seem to be run chrooted. LDAPsearch works just fine (in 
fact testing with ldapsearch in verbose mode pointed out the certificate 
problem which was solved with the TLS_REQCERT setting).

Any ideas on how to solve this problem are welcome.
