LDAP routing stuff
A variety of notes on LDAP routing in Sendmail…
- LDAPROUTE_EQUIVALENT (or the corresponding file of domains) searches the LDAP server for the domain that you’re masquerading as. cf/README even says this. Don’t forget it and forget to set a masquerading domain if you’re using it.
- You can have multiple LDAPROUTE_DOMAINs, if you like. They’ll use the same LDAP lookup syntax, though. But at least they’ll look for different domains in the LDAP server.
- If you’ve got aliases in LDAP, an MX will treat them as aliases and try to expand them, even if you think you want to have it pass them off to a mailHost for that host to expand. At least as far as I can determine. So you’ll have to put aliases in different parts of the tree for different servers to access, depending on who’s supposed to be doing the expansions. Maybe the doco and suggested tree for aliases already does this, but we relish being non-standard here.
- When it works right, LDAP routing is really really handy.
- There’s something screwy going on with the OpenLDAP proxy cache that the first time it returns an uncached response Sendmail doesn’t like it. After it’s cached, all is well. Weird.
