- 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.
- Removed LDAP specific logic from login controller, placed in Guard.
- Created safer base user provider for ldap login, to be used for SAML
soon.
- Moved LDAP auth work from user provider to guard.
- Allows the field that gets stored as the "External Authentication ID"
to be configurable. Defined as LDAP_ID_ATTRIBUTE=uid in .env.
- Added test to cover usage.
- Also now auto-lowercases when searching for attributes in LDAP
response since PHP always provides them as lower case.
Closes#592.
- Aligns with PHP behaviour where ports is ignore for full LDAP URI.
- Added tests to check format being passed to LDAP is as expected.
- May be related to #1220
- Related to #1386 and #1278
