Can't use Capitalized Policy Name to display policy even it is created using Capitalized name

[lauradiane]

Policy names in general work in a case-insensitive way. However, when you try to read a specific policy name that you've created with Capital Letters, nothing is returned. This contradicts Vault's normal behavior which is to just automatically translate it into the lower-case version.

Example:

// Write a policy with Capital Letters in the name

$ vault policy-write CapPolicy policy.hcl 
Policy 'CapPolicy' written.

// List policies and the new policy shows up converted into lowercase

$ vault policies
cappolicy
default
root

// Create a new token using any mixture of CAPS and lowercase and it will translate into the lowercase version of the policy

$ vault token-create -policy=CapPolicy
Key            	Value
---            	-----
token          	4316f873-bb06-f1bd-6b3a-ee4e148f7f09
token_accessor 	643b78bb-1866-6520-7d2a-40f44bd69d65
token_duration 	768h0m0s
token_renewable	true
token_policies 	[cappolicy default]

// Bug: Try listing the policy by name using the Capitalized version and nothing is returned (doesn't map back to lowercase version as it did for other Vault commands)

$ vault policies CapPolicy
<blank output>
