Switch the mediawiki LDAP setup to a new application account
Needs the new directory structure:
```
dn: cn=applications,dc=kosmos,dc=org
objectClass: top
objectClass: organizationalRole
cn: users
dn: ou=kosmos.org,cn=applications,dc=kosmos,dc=org
objectClass: top
objectClass: organizationalUnit
ou: kosmos.org
dn: ou=5apps.com,cn=applications,dc=kosmos,dc=org
objectClass: top
objectClass: organizationalUnit
description: 5apps
ou: 5apps.com
dn: uid=wiki,ou=kosmos.org,cn=applications,dc=kosmos,dc=org
objectClass: simpleSecurityObject
objectClass: account
uid: wiki
userPassword: [snip]
dn: uid=xmpp,ou=kosmos.org,cn=applications,dc=kosmos,dc=org
objectClass: simpleSecurityObject
objectClass: account
uid: xmpp
userPassword: [snip]
dn: uid=xmpp,ou=5apps.com,cn=applications,dc=kosmos,dc=org
objectClass: simpleSecurityObject
objectClass: account
uid: xmpp
userPassword: [snip]
```
And the new ACIs:
```
dn: ou=5apps.com,cn=users,dc=kosmos,dc=org
