Apache core dump when using LDAP authentification.





------- Additional Comments From apache@schiegl.com  2003-09-20 12:39 -------
to summarize a few observations i made with 2.0.47, worker-mpm, solaris8 and 
openldap2.1.22:

1.) i must place the following statements outside of any virtual host 
statement otherwise the ldap-cache will not work (checked with the
ldap-status handler).

LDAPSharedCacheSize 200000
LDAPCacheEntries 1024 <- this seems to be the important one
LDAPCacheTTL 600
LDAPOpCacheEntries 1024
LDAPOpCacheTTL 600
[LDAPSharedCacheFile logs/ldap_cache_file]

using this configuration the ldap-cache seems to initialize just fine, e.g.
...
Cache Name Entries Avg. Chain Len. Hits Ins/Rem Purges Avg Purge Time 
LDAP URL Cache 0 (0% full) 0.0 0/0 100% 0/0 (none) 0 
...

but after the first successfull authentication the connection aborts.
error_log:
...
[Sat Sep 20 14:18:35 2003] [notice] child pid 14848 exit signal Bus error (10)
...

2. placing the above statement inside a virtual-host statement or setting the 
parameter LDAPCacheEntries to 0, results in a disabled LDAP cache, but 
authentication works at least.

3. applying the latest patch from Matthieu Estrade (09/12/03) doesn't help 
either. httpd creates a 6 byte LDAPSharedCacheFile, but the results are the 
same listed in 1) and 2)
