Versions of {product-short} prior to {product-version} stored ephemeral data in LDAP. Examples of ephemeral data include:
-
zimbraAuthTokens
-
zimbraCsrfTokenData
-
zimbraLastLogonTimestamp
{product-name} version {product-version} introduced the ability to store ephemeral data in an external service such as SSDB. This is an optional feature; however, it can improve LDAP performance and stability.
Please refer to the {product-admin-guide} for more information. Migration of ephemeral data out of LDAP and into SSDB must be performed after an install or upgrade has been completed.
