The modschema.log file contains the results of all schema extensions that are applied when an eDirectory server is installed into an existing tree. Each line of the log states which class or attribute is being added or modified and gives the status of the modification attempt.
This log is created or overwritten each time the install process is run, so it only represents the results of the last attempt. In addition to the eDirectory schema extensions, this log contains the results of any other schema extensions, such as the Lightweight Directory Access Protocol (LDAP) or SAS, applied by the DSINSTALL front end prior to adding the new eDirectory server.
This log will not be generated when a standalone server is installed or if the version of the target server is eDirectory 7.0.1 or later.
