You can upload new attributes through the Identity Manager to extend the schema. The following steps explain the procedure to extend the schema:
Navigate to the extracted driver zip folder > schema.
Copy the epicID.sch file to the system where Identity Manager is installed.
Execute the following ndssch command.
ndssch [-h hostname[:port]] [-t tree_name] [-d] admin_FDN schemafile [schema_description]
For example, ndssch -h 10.71.131.123:524 -t SLES12SP3_Quality_131123_TREE -d admin.sa.system /root/schema/epicID.sch
The log file is created in the default location, /root/schema.log for troubleshooting.
Restart Identity Manager to see the schema changes.
