If you add an attribute for encryption using LDIF, do not associate duplicate algorithms with one attribute.
For example, marking title as an encrypted attribute with AES and DES encryption algorithms makes it unclear as to which algorithm is ultimately considered. Each time when limber is run it appears the title attribute toggles between AES and DES. Therefore, it seems as though there were some configuration changes.
To prevent such scenarios, we recommend you to avoid duplicate algorithms been assigned to the same attribute.
This does not happen if you mark an attribute for encryption using iManager.
