Is LDAP client implementation missing scope setting?

[anarion80]

Hello,

I have setup Release Bell in my own environment using docker. Everything is up and running, but I can't login using LDAP.

=> Create database.json
=> Run db-migration
Ignoring invalid configuration option passed to Connection: driver. This is currently a warning, but in future versions of MySQL2, an error will be thrown if you pass an invalid configuration option to a Connection
[INFO] No migrations to run
[INFO] Done
=> Start application
Can send emails. Email notifications are sent out as [email protected]
Use ldap auth
Server is up and running on port 3000

I have the following env (actual domain removed):

CLOUDRON_APP_ORIGIN = example.com
CLOUDRON_LDAP_BIND_DN = cn=admin,dc=example,dc=com
CLOUDRON_LDAP_BIND_PASSWORD = password
CLOUDRON_LDAP_URL = ldap://openldap:1389
CLOUDRON_LDAP_USERS_BASE_DN = ou=users,dc=example,dc=com
CLOUDRON_MYSQL_DATABASE = releasebell
CLOUDRON_MYSQL_HOST = mariadb
CLOUDRON_MYSQL_PASSWORD = password
CLOUDRON_MYSQL_PORT = 3306
CLOUDRON_MYSQL_USERNAME = releasebell

when I enter username and password though, I get 401 and "Invalid username or password" message.

At that time my LDAP server is showing:

BIND dn="cn=admin,dc=example,dc=com" method=128
BIND dn="cn=admin,dc=example,dc=com" mech=SIMPLE bind_ssf=0 ssf=0
RESULT tag=97 err=0 qtime=0.000027 etime=0.000272 text=
SRCH base="ou=users,dc=example,dc=com" scope=0 deref=0 filter="(|(uid=anarion)(mail=anarion)(?username=anarion)(?sAMAccountName=anarion))"
SEARCH RESULT tag=101 err=0 qtime=0.000019 etime=0.000192 nentries=0 text=

so 0 entries/results.

when I do the same using ldapsearch command, I get:

BIND dn="cn=admin,dc=example,dc=com" method=128
BIND dn="cn=admin,dc=example,dc=com" mech=SIMPLE bind_ssf=0 ssf=0
RESULT tag=97 err=0 qtime=0.000031 etime=0.000507 text=
SRCH base="ou=users,dc=example,dc=com" scope=2 deref=0 filter="(|(uid=anarion)(mail=anarion)(?username=anarion)(?sAMAccountName=anarion))"
RESULT tag=101 err=0 qtime=0.000045 etime=0.000888 nentries=1 text=

So the user is found. The only difference is scope.

In your code you seem to be using the default, which is base (or 0) link:
ldapClient.search(process.env.CLOUDRON_LDAP_USERS_BASE_DN, { filter: filter }, function (error, result)
while ldapsearch command by default uses sub which is wholeSubtree.

I think that we can't really search for users in a tree using base, as that's only the level of base DN.
Can you consider adding the scope attribute there?

Or how are you using LDAP otherwise?
