When i try to run php4 (as a module from apache) i also compiled php4 with
oracle 8 support (oracle and oci8), it crashes every time it reads my
libnss-ldap.conf which has my host, my base and my ldap version (in this
case its v3) only those 3 lines, which is needed for others programs to
access my ldap base.
When i remove the file libnss-ldap.conf , php4 load normally without
segmentat faulting, anyway when i dont load the php4 module , apache works
fine, so it isnt a bug in apache, but in the php4, i also tried php 4.3.4
and 4.1.2 but still gave me the same.
for now i have disabled php4 and im running with apache (1.3.29) and
coldfusion mx 6.1 without any problems.
a small fix imho would make php not read this file, but well i dont know
WHY it reads it and which impacts would if he doesnt read.
i hope i can get some help about this stuff, either if i can get a patch
(or tell me which part in code) it does this call open().
any help is appreciated.
thanks in advance.
