20.6.2. Configuring the Authentication Service
22.214.171.124. Integrating with the Keystone Authentication Service
- To configure Keystone, add
/etc/swift/proxy-server.confpipeline as shown below:
[pipeline:main] pipeline = catch_errors healthcheck proxy-logging cache authtoken keystoneauth proxy-logging proxy-server
- Add the following sections to
/etc/swift/proxy-server.conffile by referencing the example below as a guideline. You must substitute the values according to your setup:
[filter:authtoken] paste.filter_factory = keystoneclient.middleware.auth_token:filter_factory signing_dir = /etc/swift auth_host = keystone.server.com auth_port = 35357 auth_protocol = http auth_uri = http://keystone.server.com:5000 # if its defined admin_tenant_name = services admin_user = swift admin_password = adminpassword delay_auth_decision = 1 [filter:keystoneauth] use = egg:swift#keystoneauth operator_roles = admin, SwiftOperator is_admin = true cache = swift.cache
Verify that the Red Hat Storage Object Store has been configured successfully by running the following command:
$ swift -V 2 -A http://keystone.server.com:5000/v2.0 -U tenant_name:user -K password stat
126.96.36.199. Integrating with the GSwauth Authentication Service
Perform the following steps to integrate GSwauth:
- Create and start a Red Hat Storage volume to store metadata.
# gluster volume create NEW-VOLNAME NEW-BRICK # gluster volume start NEW-VOLNAMEFor example:
# gluster volume create gsmetadata server1:/exp1 # gluster volume start gsmetadata
gluster-swift-gen-builderstool with all the volumes to be accessed using the Swift client including
# gluster-swift-gen-builders gsmetadata other volumes
- Edit the
/etc/swift/proxy-server.confpipeline as shown below:
[pipeline:main] pipeline = catch_errors cache gswauth proxy-server
- Add the following section to
/etc/swift/proxy-server.conffile by referencing the example below as a guideline. You must substitute the values according to your setup.
[filter:gswauth] use = egg:gluster_swift#gswauth set log_name = gswauth super_admin_key = gswauthkey metadata_volume = gsmetadata auth_type = sha1 auth_type_salt = swauthsalt
ImportantYou must ensure to secure the
proxy-server.conffile and the
super_admin_keyoption to prevent unprivileged access.
- Restart the proxy server by running the following command:
# swift-init proxy restart
You can set the following advanced options for GSwauth WSGI filter:
- default-swift-cluster: The default storage-URL for the newly created accounts. When you attempt to authenticate for the first time, the access token and the storage-URL where data for the given account is stored will be returned.
- token_life: The set default token life. The default value is 86400 (24 hours).
- max_token_life: The maximum token life. You can set a token lifetime when requesting a new token with header
x-auth-token-lifetime. If the passed in value is greater than the
max_token_life, then the
max_token_lifevalue will be used.
GSwauth provides CLI tools to facilitate managing accounts and users. All tools have some options in common:
- -A, --admin-url: The URL to the auth. The default URL is
- -U, --admin-user: The user with administrator rights to perform action. The default user role is
- -K, --admin-key: The key for the user with administrator rights to perform the action. There is no default value.
Prepare the Red Hat Storage volume for
gswauth to save its metadata by running the following command:
# gswauth-prep [option]
# gswauth-prep -A http://10.20.30.40:8080/auth/ -K gswauthkey
188.8.131.52.1. Managing Account Services in GSwauth
Create an account for GSwauth. This account is mapped to a Red Hat Storage volume.
# gswauth-add-account [option] <account_name>
# gswauth-add-account -K gswauthkey <account_name>
You must ensure that all users pertaining to this account must be deleted before deleting the account. To delete an account:
# gswauth-delete-account [option] <account_name>
# gswauth-delete-account -K gswauthkey test
Sets a service URL for an account. User with
reseller admin role only can set the service URL. This command can be used to change the default storage URL for a given account. All accounts will have the same storage-URL as default value, which is set using
# gswauth-set-account-service [options] <account> <service> <name> <value>
# gswauth-set-account-service -K gswauthkey test storage local http://newhost:8080/v1/AUTH_test
184.108.40.206.2. Managing User Services in GSwauth
The following user roles are supported in GSwauth:
- A regular user has no rights. Users must be given both read and write privileges using Swift ACLs.
adminuser is a super-user at the account level. This user can create and delete users for that account. These members will have both write and read privileges to all stored objects in that account.
reseller adminuser is a super-user at the cluster level. This user can create and delete accounts and users and has read and write privileges to all accounts under that cluster.
- GSwauth maintains its own swift account to store all of its metadata on accounts and users. The
.super_adminrole provides access to GSwauth own swift account and has all privileges to act on any other account or user.
The following table provides user access right information.
Table 20.1. User Access Matrix
|Role/Group||get list of accounts||get Acccount Details||Create Account||Delete Account||Get User Details||Create admin user||Create reseller_admin user||Create regular user||Delete admin user|
|regular user (type)|
You can create an user for an account that does not exist. The account will be created before creating the user.
-rflag to create a
reseller adminuser and
-aflag to create an
adminuser. To change the password or role of the user, you can run the same command with the new option.
# gswauth-add-user [option] <account_name> <user> <password>
# gswauth-add-user -K gswauthkey -a test ana anapwd
Delete a user by running the following command:
gswauth-delete-user [option] <account_name> <user>
gwauth-delete-user -K gswauthkey test ana
There are two methods to access data using the Swift client. The first and simple method is by providing the user name and password everytime. The swift client will acquire the token from gswauth.
$ swift -A http://127.0.0.1:8080/auth/v1.0 -U test:ana -K anapwd upload container1 README.md
curl -v -H 'X-Storage-User: test:ana' -H 'X-Storage-Pass: anapwd' -k http://localhost:8080/auth/v1.0 ... < X-Auth-Token: AUTH_tk7e68ef4698f14c7f95af07ab7b298610 < X-Storage-Url: http://127.0.0.1:8080/v1/AUTH_test ...
$ swift --os-auth-token=AUTH_tk7e68ef4698f14c7f95af07ab7b298610 --os-storage-url=http://127.0.0.1:8080/v1/AUTH_test upload container1 README.md README.md bash-4.2$ bash-4.2$ swift --os-auth-token=AUTH_tk7e68ef4698f14c7f95af07ab7b298610 --os-storage-url=http://127.0.0.1:8080/v1/AUTH_test list container1 README.md
Reseller adminsmust always use the second method to acquire a token to get access to other accounts other than his own. The first method of using the username and password will give them access only to their own accounts.
220.127.116.11.3. Managing Accounts and Users Information
You can obtain the accounts and users information including stored password.
# gswauth-list [options] [account] [user]
# gswauth-list -K gswauthkey test ana +----------+ | Groups | +----------+ | test:ana | | test | | .admin | +----------+
- If [account] and [user] are omitted, all the accounts will be listed.
- If [account] is included but not [user], a list of users within that account will be listed.
- If [account] and [user] are included, a list of groups that the user belongs to will be listed.
- If the [user] is .groups, the active groups for that account will be listed.
-poption provides the output in plain text format,
-jprovides the output in JSON format.
You can change the password of the user, account administrator, and reseller_admin roles.
- Change the password of a regular user by running the following command:
# gswauth-add-user -U account1:user1 -K old_passwd account1 user1 new_passwd
- Change the password of an
account administratorby running the following command:
# gswauth-add-user -U account1:admin -K old_passwd -a account1 admin new_passwd
- Change the password of the
reseller_adminby running the following command:
# gswauth-add-user -U account1:radmin -K old_passwd -r account1 radmin new_passwd
.super_admin role can delete the expired tokens.
# gswauth-cleanup-tokens [options]
# gswauth-cleanup-tokens -K gswauthkey --purge test
- -t, --token-life: The expected life of tokens. The token objects modified before the give number of seconds will be checked for expiration (default: 86400).
- --purge: Purges all the tokens for a given account whether the tokens have expired or not.
- --purge-all: Purges all the tokens for all the accounts and users whether the tokens have expired or not.

126.96.36.199. Using Object Expiration
The X-Delete-At header requires a UNIX epoch timestamp, in integer form. For example, 1418884120 represents Thu, 18 Dec 2014 06:27:31 GMT. By setting the header to a specific epoch time, you indicate when you want the object to expire, not be served, and be deleted completely from the Red Hat Storage volume. The current time in Epoch notation can be found by running this command:
$ date +%s
- Set the object expiry time during an object PUT with X-Delete-At header using cURL:
curl -v -X PUT -H 'X-Delete-At: 1392013619' http://127.0.0.1:8080/v1/AUTH_test/container1/object1 -T ./localfileSet the object expiry time during an object PUT with X-Delete-At header using swift client:
swift --os-auth-token=AUTH_tk99a39aecc3dd4f80b2b1e801d00df846 --os-storage-url=http://127.0.0.1:8080/v1/AUTH_test upload container1 ./localfile --header 'X-Delete-At: 1392013619'
The X-Delete-After header takes an integer number of seconds that represents the amount of time from now when you want the object to be deleted.
- Set the object expiry time with an object PUT with X-Delete-After header using cURL:
curl -v -X PUT -H 'X-Delete-After: 3600' http://127.0.0.1:8080/v1/AUTH_test/container1/object1 -T ./localfileSet the object expiry time with an object PUT with X-Delete-At header using swift client:

188.8.131.52. Running Object Expirer Service
/etc/swift/object-expirer.conffile. For every pass it makes, it queries the gsexpiring account for tracker objects. Based on the timestamp and path present in the name of tracker objects, object-expirer deletes the actual object and the corresponding tracker object.
# swift-init object-expirer start
# swift-object-expirer -o -v /etc/swift/object-expirer.conf

/mnt/gluster-object). The default value can be changed to a different path by changing the
devicesconfigurable option across all account, container, and object configuration files. The path must contain Red Hat Storage volumes mounted under directories having the same names as volume names. For example, if
devicesoption is set to
/home, it is expected that the volume named
testvol1be mounted at
gluster-swift-gen-builderstool even if it was previously added. The
gluster-swift-gen-builderstool creates new ring files every time it runs successfully.
