const pathPolicyHelpSyn = `

Read and write IAM policies that access keys can be made for.
|

`
|
|
|
|
const pathPolicyHelpDesc = `
|
|
This path allows you to read and write policies that are used to
|
|
create access keys. These policies map directly to the route to read the
|
|
access keys. For example, if the backend is mounted at "aws" and you
|
|
wrote a policy to "aws/policy/deploy" then a user could request access
|
|
credentials at "aws/deploy".
|
|
|
|
The policies written are normal IAM policies. Vault will not attempt to
|
|
parse these except to validate that they're basic JSON. To validate the
|
|
keys, attempt to read an access key after writing the policy.
