RE: Email address verification

Yes. The file in the IFS is names.nsf. However, that may be a bit hard for you to analyze. Your Domino server is not currently set up to export the names.nsf on a periodic basis so, since your Domino team is opposed to any change, I don't see that happening any time soon. Now, if you want to manually go into File, Export Contacts and mess around with that you can.

Funny thing is, your Domino server is probably already set up to serve ldap and they don't even know it. It's a default on your primary NAB server.

Is it using ldap over SSL or not? If the above says Port:389 it is not using ssl. 636 is the port for SSL.

Or WRKJOB LDAP

$

Ldapsearch -h notes01.corp.dekko.com -s base -D "cn=Rob Berendt,O=DEKKO" -w PlacePasswordHere "cn=*guebard*"

The -D is used to say the next parameter is the user to bind to the DNS with. The -w is the password.

Here, we serve up ldap from Domino for use by our printer/scanners to send scanned documents to. And a bunch of other stuff. How does your printer scanners do their ldap search? Can you use ldapsearch on that? You may have to add parameters for a binding name and password. Any google search for ldapsearch will show you how to do that. I showed an example above. Windows Active Directory often has email addresses stored in that also. You could ldapsearch that. Then next year when you migrate to Azure for active directory you can rewrite it.

Boy am I looking forward to my day off on Monday...
