Hi,

Thanks in advance for helping me.

my ladap user on production server is “viman”  
my sudo su user on production server is “cassdb”

I am trying to execute commands as cassdb user like id, ps -ef|grep …,

but it gives error

10.45.206.104 | FAILED! =\> {  
“changed”: false,  
“failed”: true,  
“module\_stderr”: “”,  
“module\_stdout”: “\r\nSorry, user viman is not allowed to execute ‘/bin/sh -c echo BECOME-SUCCESS-uqhffxyayhqcqqdiouilnxxqumlcxobw; /usr/bin/python /tmp/ansible-tmp-1495268464.677336-247138043012258/command.py’ as cassdb on [TXN-cappblx042-03.prod.XXXY.com](http://TXN-cappblx042-03.prod.XXXY.com).\r\n”,  
“msg”: “MODULE FAILURE”,

commands I used tried are

ansible all -b -m shell -a ‘id -a’ --become-user=cassdb

It's not possible to combine sudo with su in Ansible, you need to choose one of them.
