Re: Apache 2.2 not working with LDAP Fail Over Auth

HI Eric

I can close browser and access url again but this time no error comes in error log file in debugging mode, but my request url is currently still in processing and apache is trying to seek ldap1.

Hi Eric

Below comes in apache debug logs when primary ldap1 is unreachable or down.

Apache tells the LDAP library the timeout you've specified, and passes
the two hostnames to the LDAP library unmodified.  The LDAP library is
the one  that has to understand the meaning of providing the two
hostnames, and when/how to fail over.

Perhaps your Apache is linked with a different library then the other
software on your system if the other software handles both cases.
pmap or lsof or fuser will tell you what LDAP library is loaded by the
different pieces of software at runtime.

The debug library I linked to in my first response might provide
additional messages from the LDAP library itself, but since you
haven't even included the LogLevel debug messages from Apache after 8
emails on the subject, that might be asking a lot.
