Certificate Subject Alternative Names are limited to 1023 characters.


A certificate's Subject Alternative Name is not correct in the BIG-IP configuration. This does not impact the BIG-IP system's ability to select the proper Client SSL profile on a virtual server that uses SNI matching to provide distinct certificates.


Using a certificate with a Subject Alternative Name longer than 1023 characters.


Specify fewer than 1023 character for the Certificate Subject Alternative Names.
