I am trying to create a ODBC connection to a SQL server instance from my RStudio server on Debian 9.
As the username i have to access the DB is registered under a windows domain, i went through the kerberos installation process. I already installed and configured Kerberos client and its working ok. After running kinit i get no output 
:
admonda@campbell:/etc$ kinit -f username
Password for username@YYYYY.NET:
admonda@campbell:/etc$
Going back to R, when trying to create the connection, i get a kerberos error. I think im half way but missing something
library(RODBC)
library(odbc)
con <- dbConnect(odbc::odbc(),
Driver = "ODBC Driver 17 for SQL Server",
server = "172.30.19.66\\mydb", # remember \\ if your path has a \
database = "mydb1",
uid = "YYYYY\\username",
pwd = "mypassword",
Trusted_Connection= "Yes" )
