> In some cases the KnoxLdapRealm will not work unless the
> KnoxLdapContextFactory is also configured. In particular the use of an
> ${ALIAS=...} in the >main.ldapRealm.contextFactory.systemPassword param. As
> this is such a common and important use cases the KnoxLdapContextFactory
> should be included in all default topology files, all sample topology files
> and all documented topology files.
> The snippet below shows what needs to be added to the topology files.
> {code:xml}
> <topology>
> <gateway>
> <provider>
> <role>authentication</role>

> Without this in particular there were exceptions in the gateway.log file at
> startup when password indirection was used in the ShiroProvider section like
> this.

> <param>
> <name>main.ldapRealm.contextFactory.systemPassword</name>
> <value>${ALIAS=adSysPwd}</value>
> </param>
> {code}
> Those exceptions look like this. Indicating that the wrong
> LdapContextFactory was being used. Specifically the default one that does
> not have a setClusterName method.
