[PHP-INSTALL] Funny issue with php5, solaris 10, apache2, ldapclient

[kjc]

I've got a funny issue, and it has been narrowed down to something with PHP5 on my Solaris10 boxes.

the S10 boxes are running as LDAP clients (using LDAP instead of NIS) in the proxy configuration, pam_unix.
With the PHP5 module loaded the Apache daemon user does not know of his secondary groups, only his primary group as defined in the httpd.conf plus any local groups in /etc/group if there are any. Which I don't want there to be, because that's the purpose of using the LDAP.

I took the Apache supplied printenv perl script in cgi-bin and added this info to demonstrate the problem:
print "Data about the running process:<BR>
  <pre>
  Real user id       : $<
  Effective user id  : $>
  Real group id      : $(
  Effective group id : $)
  </pre><br>\n";

The output with PHP5 module loaded, where 99 is a local group and 42 is the default group (and in ldap):

  Real user id       : 10 
  Effective user id  : 10 
  Real group id      : 42 99 42 
  Effective group id : 42 99 42  

The output without PHP5 loaded:

  Real user id       : 10 
  Effective user id  : 10 
  Real group id      : 42 7000 775 124 60010 602 60009 125 216 60008 42 
  Effective group id : 42 7000 775 124 60010 602 60009 125 216 60008 42  
  

I've tried recompiling PHP with and without LDAP libraries, --enable-yp...
I played with the safe_mod and safe_mode_gid settings, setting them 0,1, 1,1, 0,0 and had no change.

I am running both Apache and PHP with full 64bit binaries. That was no small feat.

Any ideas or help?
