Keystone Validation Error Code 404

Oliver Wehrli — Tue, 14 Oct 2014 09:25:17 GMT

Dear community,

**Update**

On my HP VAN SDN Controller v2.3.5 I continuously receive the following error:

Failed to validate token f16056645b7a486f9112d68a573377bf due to com.hp.api.auth.AuthenticationException: Validation error code 404.

The error keeps reappearing in intervals of a few minutes.

Any input on the root cause of this error and how to resolve it would be highly appreciated. If you need any additional input please let me know.

Regards

Hi Oliver,

I have seen this before. In my case, it was a broswer window that has been open for longer than the token expiration time. Try closing all browsers that are connected to protector and re-launching.

Hi Eric,

I've monitored the situation for a few days now. I see the error reappearing every once in a while, but not in the frequency that I had before.

It appears that this has been the root cause after all.

Thank you very much and best regards,

Oliver

Hello,

After you reinstalled keystone, did you check whether the sdn user is present in keystone?

keystone --os-endpoint http://127.0.0.1:35357/v2.0 --os-token ADMIN user-list

keystone --endpoint http://127.0.0.1:35357/v2.0 --token ADMIN user-list

the above depending from the keystone version running.

If the user is not there, please try to create it executing the script:

sudo /opt/sdn/admin/config_local_keystone

as from the installation guide.

Antonio

Yes The user are in keystone.

The strange thing is i can do CURL via command line successfully , but i am unable to login to UI even after i restart the browser

/usr/bin/curl -sk -H Content-Type:application/json -d {"login":{"user":"sdn","password":"skyline","domain":"sdn"}} https://172.16.4.8:8443/sdn/v2.0/auth
{"record":{"token":"59a27f7d913e4cb1adaae3bd74253ca4","expiration":1432780102000,"expirationDate":"2015-05-27 22-28-22 -0400","userId":"05fd7f1101814ea7a526cb59dfb04860","userName":"sdn","domainId":"ae3ef03bbfc44ad2a90ea5173aa1dc31","domainName":"sdn","roles":["sdn-user","sdn-admin"]}}

Hi,

Then I suspect the issue is on the keystone.conf file.

As explained the installation manual:

UUID is the default provider type for the Folsom release of Keystone. However, if the remote machine

supporting your Keystone server is running the Grizzly, Havana, or Icehouse version of Keystone

(which all use the PKI provider type), edit the /etc/keystone/keystone.conf file on your

Keystone server by adding the following line to set UUID as the provider type:

provider=keystone.token.providers.uuid.Provider

Can you please check whether the setting is correct on your file.

If not present please add it to the file accordingly (as from the manual):

# Options defined in keystone

# External auth mechanisms that should add bind information to

# token e.g. kerberos, x509. (list value)

#bind=

# Enforcement policy on tokens presented to keystone with bind

# information. One of disabled, permissive, strict, required

# or a specifically required bind mode e.g. kerberos or x509

# to require binding to that authentication. (string value)

#enforce_token_bind=permissive

# Amount of time a token should remain valid (in seconds).

# (integer value)

#expiration=3600

# Controls the token construction, validation, and revocation

# operations. Core providers are

# "keystone.token.providers.[pki|uuid].Provider". (string

# value)

provider=keystone.token.providers.uuid.Provider1

# Keystone Token persistence backend driver. (string value)

#driver=keystone.token.backends.sql.Token

# Toggle for token system cacheing. This has no effect unless

# global caching

Let me know whether this solves the issue.

Regards,

Antonio
