Novell iManager 2.7
Modifying the various time-based attributes on objects in eDirectory via iManager does not allow those values to be later than early in the year 2038. These include Login Expiration Time and Password Expiration Time among others.
This is a limitation in iManager caused by the interpretation of the time attributes as being signed integers when they are actually unsigned integers. eDirectory already supports these larger values up to the year 2108. The issue will be resolved in a Service Pack (SP) of iManager and in future major releases of iManager. In the meantime LDAP can be used to modify values so they are set to the years beyond 2038.
