Caliber LDAP & Integrated Windows Authentication Fails
The IWA integration can fail after a certain amount of time. This is due to the LDAP system returning more than 5000 records for a query. This can be resolved by changing the LDAP port to 3289 which reduces the amount of data returned preventing the failure.
"Port 389 Returns a search for objects from this domain. It has a complete set of all attributes each object contains, whereas 3289 is attaching to the Global Catalog. The Global Catalog is a Read Only replica which contains a Partial Attribute Set (PAS) of objects within the forest, so it holds certain replicate objects from all domains."
