Update bdii-slapd-start for IPv6 support

[ellert]

Summary

I would like to propose an alternative solution to #50. I find this solution less confusing since it does not use bash arrays.

Related issue : #50

Hi @ellert ! Thanks very much.

I will take a look at this too and let you know. Since we can either merge #48 or #51 but not both, I want to have a closer look and add a functional test.

I'll get back in a few days.

So far I have tested the change with the artifact built in this run:

• the configuration file is ok
• slapd listens on IPv6 on lo the public interface --

[root@almalinux-s-1vcpu-1gb-ams3-01 ~]# ldapsearch -x -H "ldap://[2a03:b0c0:2:d0::1712:3001]:2170" -b 'Mds-Vo-Name=$SITE_NAME,o=Grid'  '(ObjectClass=GlueSite)'
# extended LDIF
#
# LDAPv3
# base <Mds-Vo-Name=$SITE_NAME,o=Grid> with scope subtree
# filter: (ObjectClass=GlueSite)
# requesting: ALL
#

# search result
search: 2
result: 32 No such object
matchedDN: o=grid

# numResponses: 1

So I think we can merge.
