[resolved] mongodb compatibility with talend

[Anonymous]

Hi All,
I m using talend 5.6.1 version and mongodb of 3.0 version
while trying to access t_mongodboutput.
 I m getting error viz., " failed to authenticate <user>@<databasename> with MONGODB-CR mechanism : Authentication failed MONGODB-CR credentials missing in user file".
this error occurs at mongodb side. Is there any way to change the authentication mechanism in talend side
please help me resolve this issue.
and also I m able to login to mongodb with mongo.exe.
P.S my project works well when I try to connect to mongodb of version 2.6.

Hi,
This error is because you have entered the wrong credentials.
Instead of providing the authentication just create a connection using server,port and database name.
Use the same connection in the output also. Make sure that the provided details should be work properly to connect to the mongodb.

did you see this example :
https://help.talend.com/pages/viewpage.action?pageId=37850494#andy-20120913-bigdata-tmongodboutput-C...
do you try 'required authentification' option.
