Thanks!

Try like below

dn: sendmailMTAKey=testuser,dc=example,dc=com objectClass: sendmailMTA objectClass: sendmailMTAAlias objectClass: sendmailMTAAliasObject sendmailMTAAliasGrouping: aliases sendmailMTACluster: ldapter-cluster

sendmailMTAKey: testuser sendmailMTAKey: tuser sendmailMTAKey: testu sendmailMTAKey: test.user sendmailMTAKey: test_user sendmailMTAAliasValue:test_user@example.com mailto:test_user@example.com

sendmailMTAAliasValue: user.tes

replace the cluster name with the one you have mentioned insendmail.mc http://sendmail.mc file

Once the above entries are added to ldap server, please test using sendmail -bv command and see whether it returns the correct results or not.

Add the server address and basedn to /etc/openldap/ldap.conf file.

schemas that have application specific names in them (sendmailMTA*) make me shiver. Seems to defeat the purpose of a directory server.

I'm leaning towards using mailGroup as it does seem to be in 389 (though I needed to make some changes there due to trying to implement ldap routing as well) and as the postfix howto mentions it seems usable there too. With sendmail one does:

define(`ALIAS_FILE', `ldap:-k (&(objectClass=mailGroup)(mail=%0)) -v mgrpRFC822MailMember')

Now if I can only figure out how to use /etc/aliases + ldap in sendmail, if possible.
