[factorio_development.sh] Added (personal) workaround for tag signing:
- Older versions of git (<2.23) do not have the tag.gpgSign
option. Try to emulate it by appending the --sign option if it is
set in git configuration.

$program $version, a semi-interactive utility for checking if a CRL in LDAP
contains a specific serial number.
Usage: $program [OPTIONS] issuer serial
$program is a semi-interactive utility for checking if a CRL in LDAP contains a
specific serial number. It is useful for verifying that new CRLs are being
published to the LDAP when revoking certificates. The utility is non-interactive
unless the user is required to provide credentials for the ldapsearch utility.
The script expects two positional arguments:
issuer
The issuer argument should be set to the issuer DN of the certification
authority that has issued the CRL. This parameter will be used for locating
the CRLs in the directory tree that have been issued by target CA.
serial
The serial argument should be set to the serial number of the certificate
that has been revoked. The certificate should have been issued by the
specified issuer. This serial number will be looked-up in the matching
CRLs.
The script works by traversing the LDAP tree, looking for all entries that have
a CRL attribute. By default the script is expecting the CRLs to be located in
the attribute 'certificateRevocationList' (this can be overridden). Each CRL
will be checked for presence of the specified serial number.
Once the script is finished traversing the LDAP tree, it will output a summary
about the number of processed CRLs, and an informative message about whether the
check has failed or not. The script will return a non-zero error code if the
check has failed.
The check is considred as failed if one of the following conditions are met:
- There was no CRL in the LDAP direcotry issued by the specified CA.
- At least one CRL in the LDAP direcotry that was issued by the specified CA
does not contain the specified serial number.
The check is considred as successful if and only if there was at least on CRL
issued by the specified CA in the LDAP directory, and all of the CRLs issued by
the specified CA in the LDAP directory contain the specified serial number.
The script relies on using the ldapsearch utility from OpenLDAP for traversing
the LDAP directory. Any configuration settings specified in the global or local
(user's) LDAP client configuration file will be applied during
search. Additional parameters can be passed to the ldapsearch utility as well by
using the -L flag.
$program accepts the following options:
-L ldapop Pass additional option to the ldapsearch utility used for
retrieving the CRL from the LDAP database. This option can be
specified multiple times.
-a attr LDAP attribute that should contain the CRL. Default is
'certificateRevocationList'.
-v show script version and licensing information
-h show usage help
