Mmmmh. Maybe I could develop an #ifdef NO_SYSLOGD which would allow to have
this feature out of the box...

I thought of something a bit more complicated :
- "l=left,o=org" is replicated from foo.com
- "l=right,o=org" is replicated from bar.org
- if I ldap_search anything under "l=left,o=org" then the result comes from
the local host
- if I ldap_modify anything under "l=left,o=org" then the modification is
referred to foo.com
- if I ldap_search anything under "l=right,o=org" then the result comes
from the local host
- if I ldap_modify anything under "l=right,o=org" then the modification is
referred to bad.org

Is this possible?

Where can I find documentation about that?

Thank you for your help,
