Use the User Groups and Token Bulk Requests utility, import-bulk-request, to import token and user group membership requests. The RSA Authentication Manager self-service feature runs this task as a batch job.
When you run the User Groups and Token Bulk Requests utility, the time that it takes for bulk request operations to complete depends on the number of requests in the comma-separated value (CSV) input file. If you receive time-out errors, it may be that your CSV input file has too many requests. You should create multiple CSV input files and import them separately.
