SIMS 3.5 requires that new LDAP object classes and attributes be added to the schema. If you are installing SIMS 3.5 for the first time, it automatically upgrades the schema. If, however, you are upgrading to SIMS 3.5 from SIMS 3.1 or 3.2 and have already populated the LDAP directory, you must complete the following two steps:
| 1. | Modify the directory server configuration files to support the new schema. | |
| 2. | Reprocess the directory contents by using the imldifsync program to add instances of the new attributes to each subscriber's LDAP record. |
