Normally I am using *monetdbd*+"mclient" combination to use MonetDB.

Now, since I want to see the debug info in each gdk operator, I have to use *mserver5*.

I do as follows (JULY2015-SP1+ubuntu14.04):

Step1:

$ mserver5 --dbpath=${HOME}/[my_dbpath] --daemon=yes --algorithms

Step2:

In another console:

$ mclient -d [dbname] -u monetdb

password: monetdb

It replies:

InvalidCredentialsException:checkCredentials:invalid credentials for user 'monetdb'

However, user:monetdb, pwd:monetdb is the default one and I can use it successfully in *monetdbd*+"mclient" combination.

Any idea?

Thanks,
