[cups] cupsenable: Operation failed: client-error-forbidden

[Édnei Rodrigues]

Hello Guys, how are you?

So, i am configuring a Cups server and my cupsd.conf is:

SystemGroup sys root

DefaultEncryption Never

SSLListen XXXXX:443
Listen 127.0.0.1:631
Listen /var/run/cups/cups.sock

Browsing On
BrowseOrder allow,deny
BrowseAllow ALL

DefaultAuthType Basic

<Location />
   Order allow,deny
   Allow All
</Location>

<Location /admin>
  AuthType Basic
  Require user root hd vferreira hp_cups orawpmsqa
  Allow all
  Order deny,allow
</Location>

<Location /admin/conf>
  Require user root
  #CCAuthType Default
  AuthType Basic
  Require user @SYSTEM
  Order allow,deny
  Allow all
</Location>

<Policy default>
  # Job-related operations must be done by the owner or an administrator...
  <Limit Send-Document Send-URI Hold-Job Release-Job Restart-Job Purge-Jobs

    #CCAuthType Default

  AuthType Default
  Require user @SYSTEM orawpmsqa
  Order deny, allow
</Limit>

  <Limit All>

</Policy>


However, When I tried to enable a printer, i got this error:

[orawpmsqa at XXXXXX ~]$ cupsenable xeroxtestsp
cupsenable: Operation failed: client-error-forbidden
[orawpmsqa at XXXXXXX ~]$ exit


Why ? I know IF I add this user to "<Location /admin>" policy, it will
work, but...why ? In my Legacy cups server, it wasn't necessary and the the
directive "AuthType basic" worked!

My Cups: cups-1.6.3-35.el7.x86_64

Thanks!
