Full info + Solution: Thanks to @dugan and @maflister  
For those who run into this in the future here is the changes that had to be implemented:  
Installed rstudio 1.3.1093 natively with the rpm (will test with source later)  
`yum install -y rstudio-server-rhel-1.3.1093-x86_64.rpm`  
In the`template/script.sh.erb` ensure you use the following :

```auto
rserver \
 --www-port "${port}" \
 --auth-none 0 \
 --auth-pam-helper-path "${RSTUDIO_AUTH}" \
 --auth-encrypt-password 0 \
 --rsession-path "${RSESSION_WRAPPER_FILE}" \
 --server-data-dir "${TMPDIR}" \
 --secure-cookie-key-file "${TMPDIR}/rstudio-server/secure-cookie-key"

```

If you haven’t already, you need to update the `template/bin/auth` and change the ‘-ne’ flag to ‘-lt’

```auto
#!/usr/bin/env bash

# Confirm username is supplied

if [[$# -lt 1]]; then

echo "Usage: auth USERNAME"

exit 1

fi

USERNAME="${1}"

# Confirm password environment variable exists

if [[-z ${RSTUDIO_PASSWORD}]]; then

echo "The environment variable RSTUDIO_PASSWORD is not set"

exit 1

fi

# Read in the password from user

read -s -p "Password: " PASSWORD

echo ""

if [[${USERNAME} == ${USER} && ${PASSWORD} == ${RSTUDIO_PASSWORD}]]; then

echo "Successful authentication"

exit 0

else

echo "Invalid authentication"

exit 1

fi

```
