Hi,

I can't bind to ldap over an SSL connection on port 636. I use the same settings as on other services, where LDAP bind works fine.

.env config

# General auth
AUTH_METHOD=ldap

# LDAP Settings
LDAP_SERVER=ldap.avionix.ee:636
LDAP_BASE_DN=dc=ldap,dc=avionix,dc=ee
LDAP_DN=uid=randomuser,cn=users,dc=ldap,dc=avionix,dc=ee
LDAP_PASS=randomepassword.
LDAP_USER_FILTER=(&(uid=${user}))
LDAP_VERSION=3

Error message:

ErrorException in Ldap.php line 94:
ldap_bind(): Unable to bind to server: Can't contact LDAP server
in Ldap.php line 94
at HandleExceptions->handleError('2', 'ldap_bind(): Unable to bind to server: Can't contact LDAP server', '/var/www/bookstack/app/Services/Ldap.php', '94', array('ldapConnection' => resource, 'bindRdn' => 'uid=randomuser,cn=users,dc=ldap,dc=avionix,dc=ee', 'bindPassword' => 'randompassword.'))

Am I missing some configuration (i.e. deine ssl or tls)?

This might be fixed in current master branch with this pull request/merge

Hi @av8orch, Sorry to hear you're having problems with SSL LDAP. Your config looks fine, but you're likely just running into this issue: #236

SSL LDAP will be fixed in the next release, At which point you'll need to update your LDAP_SERVER setting to ldaps://ldap.avionix.ee:636.
If you need to get around the issue until the next release and you have some development experience you could apply the fix shown in #236 as a temporary fix.

Thanks @ssddanbrown and @lommes

This temporary fix did it. LDAPS now works.
