The current `admin auth` CLI for managing authentication source of type
LDAP via BindDN and Simple LDAP does not allow enabling the respective
source, once disabled via `--not-active`.
The same applies to `--synchronize-users` specifially for LDAP via
BindDN.
These changes add two new flags to LDAP related CLI commands:
- `--active` for both LDAP authentication source types
- `--disable-synchronize-users` for LDAP via BindDN
