Problem

The Admin service cannot start after deleting of the "admind" certificate from the Setup → Certificates → Local certificates page.

Resolution

1. Upload a prepared PKCS12 certificate file (.p12) to the OS.

2. If you are running with embedded DB, it must be started first:

<FILEDRIVEHOME>/bin/start_db

3. Import the certificate with the command-line tool import_certificate_authority with the below command:

<FILEDRIVEHOME>/bin/import_certificate_authority -t l -p PASSWORD_FOR_THE_P12 -a admind -f /PATH/TO/THE/P12_FILE.p12

where <FILEDRIVEHOME> represents the SecureTransport installation folder.
