SPECIAL CONFIGURATION DIRECTIVES

Target configuration starts with the "uri" directive. All the configuration directives that are not specific to targets should be defined first for clarity, including those that are common to all backends. They are:

conn-pool-max <int> This directive defines the maximum size of the privileged connections pool.

conn-ttl <time> This directive causes a cached connection to be dropped an recreated after a given ttl, regardless of being idle or not.

default-target none This directive forces the backend to reject all those operations that must resolve to a single target in case none or multiple targets are selected. They include: add, delete, modify, modrdn; compare is not included, as well as bind since, as they don't alter entries, in case of multiple matches an attempt is made to perform the operation on any candidate target, with the constraint that at most one must succeed. This directive can also be used when processing targets to mark a specific target as default.

dncache-ttl {DISABLED|forever|<ttl>} This directive sets the time-to-live of the DN cache. This caches the target that holds a given DN to speed up target selection in case multiple targets would result from an uncached search; forever means cache never expires; disabled means no DN caching; otherwise a valid ( > 0 ) ttl is required, in the format illustrated for the idle-timeout directive.

onerr {CONTINUE|report|stop} This directive allows one to select the behavior in case an error is returned by one target during a search. The default, continue, consists in continuing the operation, trying to return as much data as possible. If the value is set to stop, the search is terminated as soon as an error is returned by one target, and the error is immediately propagated to the client. If the value is set to report, the search is continued to the end but, in case at least one target returned an error code, the first non- success error code is returned.

norefs <NO|yes> If yes, do not return search reference responses. By default, they are returned unless request is LDAPv2. If set before any target specification, it affects all targets, unless overridden by any per-target directive.

noundeffilter <NO|yes> If yes, return success instead of searching if a filter is undefined or contains undefined portions. By default, the search is propagated after replacing undefined portions with (!(objectClass=*)), which corresponds to the empty result set. If set before any target specification, it affects all targets, unless overridden by any per-target directive.

protocol-version {0,2,3} This directive indicates what protocol version must be used to contact the remote server. If set to 0 (the default), the proxy uses the same protocol version used by the client, otherwise the requested protocol is used. The proxy returns unwillingToPerform if an operation that is incompatible with the requested protocol is attempted. If set before any target specification, it affects all targets, unless overridden by any per-target directive.

pseudoroot-bind-defer {YES|no} This directive, when set to yes, causes the authentication to the remote servers with the pseudo-root identity (the identity defined in each idassert-bind directive) to be deferred until actually needed by subsequent operations. Otherwise, all binds as the rootdn are propagated to the targets.

quarantine <interval>,<num>[;<interval>,<num>[...]] Turns on quarantine of URIs that returned LDAP_UNAVAILABLE, so that an attempt to reconnect only occurs at given intervals instead of any time a client requests an operation. The pattern is: retry only after at least interval seconds elapsed since last attempt, for exactly num times; then use the next pattern. If num for the last pattern is "+", it retries forever; otherwise, no more retries occur. This directive must appear before any target specification; it affects all targets with the same pattern.

rebind-as-user {NO|yes} If this option is given, the client's bind credentials are remembered for rebinds, when trying to re-establish a broken connection, or when chasing a referral, if chase-referrals is set to yes.

session-tracking-request {NO|yes} Adds session tracking control for all requests. The client's IP and hostname, and the identity associated to each request, if known, are sent to the remote server for informational purposes. This directive is incompatible with setting protocol-version to 2. If set before any target specification, it affects all targets, unless overridden by any per-target directive.

single-conn {NO|yes} Discards current cached connection when the client rebinds.

use-temporary-conn {NO|yes} when set to yes, create a temporary connection whenever competing with other threads for a shared one; otherwise, wait until the shared connection is available.
