Configuration fails with Syntax Error after upgrading to 11.5.0 from pre-11.5.0 releases.
Configuration load fails, and the system posts the alert: Syntax Error:(/config/bigip.conf at line: 12) one or more configuration identifiers must be provided.
When upgrading from a pre-11.5.0 release to version 11.5.0, the key/cert have an extra period in the name (for example mykey..key and mycert..crt). Beginning with version 11.5.0, multiple key/cert pairs are associated with one clientssl, so each key/cert pair has a name. During upgrade, the system provides a name for each key/cert, which can cause problems if the existing key/cert name contains a period character.
Manually edit the bigip.conf to add a title for the cert-key-chain, and then run the command: tmsh load sys config.
Before v11.5.0, Clientssl profile only supports one key/cert pair, no name associated with the key/cert pair. In v11.5.0, multiple key/cert pairs are associated with one clientssl, so each key/cert pair has a name.
