Access denied using mskutil

[Alberto Montes de Oca <snip3rmh@xxxxxxxxx>]

Hi, I´m trying to set up squid authentication with a Windows AD domain controller, and everything goes well until I try to check if the host account updates successfully, using the following commands:

msktutil --auto-update --verbose --dont-expire-password \

-b "CN=SQUIDPROXY,OU=OU_NAME,,DC=MYDOMAIN,DC=XX" \
--user-creds-only \
--computer-name SQUIDPROXY \
-k /etc/squid/squidproxy.keytab \
--server pdc1.mydomain.xx \

--no-reverse-lookups

and I always end up with the same error:

The account I'm using for this procedure is the domain administrator account, so I don´t know why is giving me an access denied error. This is the procedure I´m using:

1 - start the session using the domain controller account <kinit manager@xxxxxxxxxxx>

2 - created the ticket and host account in the domain controller, and everytihng went well

msktutil -c -b "OU=OU_NAME" \
-s HTTP/squidproxy.mydomain.xx \
-h squidproxy.mydomain.xx \
-k /etc/squid/squidproxy.keytab \
--computer-name SQUIDPROXY \
--upn HTTP/squidproxy.mydomain.xx \
--server pdc1.mydomain.xx \
--verbose \
--dont-expire-password \
--no-reverse-lookups \

--enctypes 28

3 - checked if the previous procedure went well by typing the following and it returns nothing as it should

kinit -k HTTP/squidproxy.mydomain.xx

4 - Checked the keytab with klist -k and then changed the permissions and owner to the keytab file (640 / proxy:proxy)

Then the error when I try to check if the host account updates succesfuly as explained at the begining, any ideas why this is happening? I would appreciate the help!!
