Hi
Is there some way of setting the maximum number of results returned from an
LDAP lookup? I believe that the LDAP URL document states that the client MAY
send this auxilliary, non-query information but that it's not part of the URL
syntax. I looked through the docs (3.00) and didn't see any reference.
At the moment some of the queries can conceivably return large %ages of the
database which is causing deferrals and memory problems. FWIW and this
may/may not be related on some of the larger queries I get exim up to over a
half-gig of memory usage, over two-thirds is resident. The debug log for one
of these queue runs is hardly over 500KB so I don't know why it's doing this.
The data is being passed into perl as in:
# This director matches everything else and attempts resolution using LDAP
aliasuser:
driver = smartuser
condition = "${perl{ldap_who} \
{${lookup ldapm {LDAP_URL(ALIAS_MATCH)}{$value} \
{${lookup ldapm {LDAP_URL(SN_MATCH)} {$value} \
{${lookup ldapm {LDAP_URL(SN2_MATCH)} {$value} \
{${lookup ldapm {LDAP_URL(CN_MATCH)} {$value} \
{${lookup ldapm {LDAP_URL(CN1_MATCH)} {$value} \
{${lookup ldapm {LDAP_URL(CN2_MATCH)} {$value} \
{${lookup ldapm {LDAP_URL(CN3_MATCH)} {$value} \
{${lookup ldapm {LDAP_URL(NOMAIL_MATCH)}{$value} \
{DUNNO}}}}}}}}}}}}}}}}}}"
new_address = ${perl{new_address}}
headers_add = "X-LDAP-Alias: V LDAP_ALIAS_VERSION. Sent to
$local_part@$domain
resolving to ${perl{new_address}}"
NOMAIL_MATCH is by that stage pretty broad (cn=*${local_part}*) which on a
short email like jo@??? returns lots of matches...
If this isn't currently possible, does anyone have any suggestions as to
temporary workarounds while a more formalised method (e.g. config option) is
developed?
Many thanks,
Paul
