Checking for transient errors.. This run, failed on OSX in two separate waysi n the become integration test:

{
    "changed": false, 
    "failed": true, 
    "module_stderr": "Traceback (most recent call last):\n  File \"/tmp/ansible_9_AciQ/ansible_module_user.py\", line 2286, in \n    main()\n  File \"/tmp/ansible_9_AciQ/ansible_module_user.py\", line 2243, in main\n    info = user.user_info()\n  File \"/tmp/ansible_9_AciQ/ansible_module_user.py\", line 621, in user_info\n    info = self.get_pwd_info()\n  File \"/tmp/ansible_9_AciQ/ansible_module_user.py\", line 616, in get_pwd_info\n    return list(pwd.getpwnam(self.name))\nKeyError: 'getpwnam(): name not found: ansibletest1'\n", 
    "module_stdout": "", 
    "msg": "MODULE FAILURE", 
    "rc": 0
}

and then

{
"changed": false, 
"err": " DS Error: -14988 (eNotYetImplemented)\n", 
"failed": true, 
"msg": "Unable to get the next available uid", 
"out": "list: DS error: eNotYetImplemented\n", 
"rc": 140
}

centos6 failure I think is due to the new tests for rpm_key. Trying to address that here: #31548
