Functionnalities:

about these secrets.

USER_LONG <description>

CMD_ONCE <command>
|

(same, but value is not changed when doing a regen)

|

CONST <constant value>
|

(the secret has a constant value set here)
|

|

CONST_LONG
|
||||
<constant value, several lines>
|

(same)
|

|

SERVICE_DN <service name> <service description>
|

(the LDAP DN of a service user)

SERVICE_PASSWORD <service name>
|

(the LDAP password for the corresponding service user)
|

|

SSL_CERT <cert name> <list of domains>
|

(a SSL domain for the given domains)
|

|

SSL_KEY <cert name>
|

(the SSL key going with corresponding certificate)
|
