- Moved the ldap function out to our separate service for easier
testing.
- Added testing for the option.
- Moved tls_insecure part back up above connection start as found more
reliable there.
Done a lot of real-connection testing during this review.
Used wireshare to ensure TLS connection does take place.
Found LDAP_TLS_INSECURE=false can action unreliably, restarting php-fpm
helped.
Tested both trusted and untrusted certificates.
Tools seems to fit better since the classes were a bit of a mixed bunch
and did not always manage.
Also simplified the structure of the SlugGenerator class.
Also focused EntityContext on shelves and simplified to use session
helper.
