MongoDBConnect: Authentication failed

I’m using this MongoDB driver for Lucee:

I’m able to authenticate with only user “admin”.

If I use the java driver directly (MongoClient), with the same connection string that I enter in MongoDBConnect(), it works.

connectionString = "mongodb://myuser:myPasSw0rd@myhost:27017";


var Mongo = CreateObject( "java", "com.mongodb.MongoClient" ).init( connectionString );

not works:

var Mongo = MongoDBConnect( "mydb", connectionString );

this is the complete error:

Timed out after 30000 ms while waiting for a server that matches ReadPreferenceServerSelector{readPreference=primary}.
Client view of cluster state is {type=UNKNOWN, servers=[{address=node223905-my-host:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=null, userName=‘useraccount’, source=‘admin’, password=, mechanismProperties={}}}, caused by {com.mongodb.MongoCommandException: Command failed with error 18: ‘Authentication failed.’ on server The full response is { “ok” : 0.0, “errmsg” : “Authentication failed.”, “code” : 18, “codeName” : “AuthenticationFailed” }}}]

Any suggestions are appreciated :slight_smile:

I think The CreateObject needs a connectionstring of “mongodb://myuser:myPasSw0rd@myhost:27017/mydb” to be equivalent. Without the /database it does admin db by default.

yes, you are right! :smiley:

you have to specify the database name twice:
in the first argument and in the connection string:


var Mongo = MongoDBConnect( "myDb", "user:pwd@host:27017/myDb" );

thanks @kabutotx! :slight_smile:
