Dear all,

I am setting up a proxy to cache queries against Active Directory, so our Postfix servers do not hammer the AD servers.

To do so I am using rwm and pcache with the following configuration:

overlay rwm rwm-normalize-mapped-attrs yes rwm-map attribute uid sAMAccountName rwm-map attribute mail proxyAddresses rwm-map attribute maildrop smtp rwm-map attribute mailbox imap rwm-map attribute domain msExchAcceptedDomainName rwm-map attribute *

tls ldaps tls_reqcert=never overlay pcache pcache bdb 10000 1 50 900 directory /var/lib/ldap/cache cachesize 10000

#index uid,mail,maildrop,mailbox eq index uid eq index mail eq

# cache configuration proxyCacheQueries 10000 pcacheAttrset 0 uid mail maildrop mailbox pcacheTemplate (uid=) 0 900 pcacheTemplate (mail=smtp:) 0 900

When running:

ldapsearch -x -LLL -E pr=200/noprompt -h 127.0.0.1 \ -D "CN=username,OU=users,DC=company,DC=com" \ -w "passsssworddddd" \ -b "OU=users,DC=company,DC=com" -s sub "(mail=smtp:me@company.com)" maildrop

It never gets cached.

query template of incoming query = (mail=) QUERY NOT ANSWERABLE QUERY NOT CACHEABLE

I have read the pcache manual many times, but I cannot find the reason. Perhaps you can find the problem.

Regards,

Xavier Garcia
