SDN/SN.IDN Size Increase

The serial number and issuer's distinguished name (SN.IDN) field size and the subject's distinguished name (SDN) field size have been increased to accommodate field sizes of up to 1024 bytes. This allows CA Top Secret to handle larger certificates generated by external certificate authorities. 1024 bytes are allowed when the SDNSIZE control option is set to 1024.

For information about the SDNSIZE control option and migration requirements for this feature, see the Control Options Guide.
