If styling hasn't been drifted too far in the custom gadgets, this should
be the case IMO.

[Dev] Clarification regarding the validating input using IdentityValidationUtil class

2016-07-15 Thread Farasath Ahamed

Hi,

I am trying to validate input using the  IdentityValidationUtil[1] class.
>From my current understanding in order to validate an input using the util
class for a regex, we need to first register it as a pattern in
IdentityValidationConfig and then use the registered key as below,

String regex = "^[A-Za-z0-9]+$";
String input = "thisismainput";


// add pattern to IdentityValidationConfig
IdentityValidationUtil.addPattern("my-regex", regex);
String validInput =
IdentityValidationUtil.getValidInputOverWhiteListPatterns(input,
"my-regex");


When many of the components start using the util class there is a
possibility of the same key being registered for two different regexes
resulting in an exception thrown according to [2]. Wouldn't it be better if
we allow the users to directly provide the regex for validation instead of
having to register it with a key and use for validation.

So if  you want to use one of the pre-defined regexes you can use the
relevant key (something like ALPHABETIC_ONLY) defined in class[1]. Or If
you want to use his own regex you can simply provide it as a whitelist
pattern.

In the code, we can first check if the provided value is a predefined key,
if so fetch the regex and validate. If the key is not found then we have
given the regex directly, so we can use it directly to validate. This
approach is used it the JavaScript util class we have written[3].

WDYT?

Re: [Dev] Add a default theme for gadgets in DS/DAS

2016-07-15 Thread Sachith Withana

Hi Jerad,

   And also this should apply to the gadgets that are generated by the
Gadget Create Wizard. Then generated gadgets will have a default theme and
gadget generator(user) does not has to worry about the styling of it,

We do write a lot of custom gadgets in analytics. Is there a way to
incorporate the solution above to those as well? So that devs writing
custom gadgets don't have to worry about their theme not syncing with other
gadgets (generated/precooked).

Regards,
Sachith

Re: [Dev] [IS-Analytics] Tenant domain of a login event using SaaS applicatioin.

2016-07-15 Thread Johann Nallathamby

I also think it is good to publish to two tenants. However we need to
validate if there are any security concerns.

E.g. let's say user John belonging to foo.com logs into travelocity.com
registered in bar.com. Tenant admin of foo.com should see it as a login
attempt in his dashboard, by one of his users for an application outside
his domain, and tenant admin of bar.com also should see it in his
dashboard, as a login attempt from a user outside his domain to one of his
apps.

Since "isUserAuthorized" method of "RemoteAuthorizationManagerService"
requires "/permission/admin/configure/security" permission, a user without
this permission will not able to access this service using his session
cookie. So your current approach is correct.

In a different thought, this kind of work arounds will cause products  to
hard to be run in a cloud environment where
you can not guarantee product startup order since containers/vm come
and go due to various reasons
Manually changing configurations also not possible in a automated
deployment environment.
So it is better if we can have a solid solution.

 @Sumedha,
 I was able to start all the nodes because the number of connections
 reduces after some time.

 As Rajith mentioned, the concern is having that number of connections
 created just for a server startup having less than 25 assets.

Noticed that it(single server startup) creates around 103 mysql connections
each time server starts and gradually reducing to smaller number(less than
10)

 My personal recommendation,
 Increase the mysql active connections to 350. Please note that this is
 bounded to server specs.
 Now start 2 servers at a time. Wait 10 mins before starting the other 2
 WSO2 servers.
 Or else you can always start 1 server at a time every 10 mins.
 Therefore it will take 30 mins to start all 4 nodes.

Re: [Dev] [BPS] BPS processes can't access when start the worker node with -DworkerNode=true

2016-07-15 Thread Hasitha Aravinda

For BPS, we are not recommending to use -DworkerNode=true in cluster,
because when server starts as a worker node, it will disable all the admin
services. But there are some user services exposed as Admin Services ( i.e
HumanTask client API, BPMN Admin services etc. ).

It seems like doc is misleading. will correct this doc.

[Dev] Controlling access to jaggery pages by permissions

2016-07-15 Thread Rajkumar Rajaratnam

Hi,

I have a jaggery app with some pages and secured them via SAML SSO with
WSO2 IS. So the authentication is implemented, now I have to implement the
authorization. I need to control access to these jaggery pages by
roles/permissions of the loggedin user. Here is the approach I have
followed and I need to validate whether it is okay or there are better
ways.

   1. Created custom permissions under my application service provider (one
   permission per one feature in my jaggery app)
   2. When a user access a feature in the jaggery app, I am calling "
   *isUserAuthorized*" method of "*RemoteAuthorizationManagerService*"
   admin service to check whether the logged in user is authorized to access
   the page. I think "isUserAuthorized" method checks whether the given user
   has any roles with the given permission. So, if it returns true, then I
   allow the user to access the page.
   3. I am calling the admin service with basic authentication. Is there
   any issues with this approach? Do I need to obtain a session cookie and
   call the admin service using session cookie instead of username/password?
   What is the recommended approach?

Any issues with this approach?
Thanks,
Raj.

[Dev] [IS-Analytics] Tenant domain of a login event using SaaS applicatioin.

2016-07-15 Thread Hasintha Indrajee

Hi All,

For SaaS application what is the tenant domain related to a login event ?
Is that the tenant domain which the SP is registered or is that the logged
in user's tenant domain ?.

If we consider sending out tenant domain as just a record, it's fine to add
either (reasonable). But the problem is we need a specific tenant domain to
publish this event. According to the current way of event publishing to the
DAS, we need to start a tenant flow before publishing. In this case we need
a specific tenant domain to publish this event. Or else do we need to
publish this event to both tenant domains (starting two tenant flows) in a
case of SaaS app ?.

Re: [Dev] [ES] Too many mysql connections when starting ES instances

2016-07-15 Thread Rajith Vitharana

Hi All,

As advised by Thushara, tried removing solr indexing in ESB using [1], but
in that case searching the registry with newly added resources fails(it
doesn't show any results). So is it ok to do this change to ESB?

[1] - registry.xml  false

 I was able to start all the nodes because the number of connections

 As Rajith mentioned, the concern is having that number of connections

This recommendation is for ES not for ESB and specially not for customers
since we can automate this using config. ES uses governance features
therefore ES need to have solr enabled. Therefore please disable[3] solr in
all ESB nodes. Further more I understand they will start all the servers
straightaway but for ES initial start(database with data) there is a heavy
indexing process is happening in the background to have a smooth ride
afterward. Since there is 4 nodes either user have to increase database
connections from DB side or start servers one by one with a delay. We can
automate this using indexingConfiguration[4] in registry.xml. This is just
a one time thing, you can change it back to default values after the first
startup.

I think we should have a shindig feature to get the current theme name,

Will this work ?

Re: [Dev] [ES] Too many mysql connections when starting ES instances

2016-07-15 Thread Chanaka Fernando

Hi Thushara,

Increase the mysql active connections to 350. Please note that this is
bounded to server specs.
Now start 2 servers at a time. Wait 10 mins before starting the other 2
WSO2 servers.
Or else you can always start 1 server at a time every 10 mins. Therefore it
will take 30 mins to start all 4 nodes.

Do you think we can tell something like this in front of a customer?
Normally customers want to start the servers within seconds and they want
to start an entire cluster within minutes (maximum). Please provide a
recommendation which makes sense in a real world. We need a proper way to
handle this.

 Guys,
 Some food for thought.

 1. A single MySQL Server has a globally defined max_connections figure
 (151 as Dilini mentioned)

 So on a clustered setup, when you point to a single MySQL Server from
 various WSO2 products, depending on no of keep alive connections specified,
 you will at some point will hit too many connections from server side @
 some point.

 So you have to rethink the deployment and use a different database
 server.

Re: [Dev] Add a default theme for gadgets in DS/DAS

2016-07-15 Thread Jerad Rutnam

Hi Udara,

Good point. Is there anyway we can look for the path
"portal\store\carbon.super\fs\theme\\css\gadget.css"
dynamically? Does shindig has any feature to achieve this?

Cheers!

 Hi Sinthuja,

 Just summarizing the offline discussion we had yesterday,

 So the basic idea is that, since we ship a default theme with the
 Dashboard Server. We should also add a default theme for precooked gadgets,
 that we ship with the Dashboard Server.

 And also this should apply to the gadgets that are generated by the
 Gadget Create Wizard. Then generated gadgets will have a default theme and
 gadget generator(user) does not has to worry about the styling of it,
 unless he/she wants a fully customized UI. We can have a configuration to
 disable this theme if anyone wants.

 If the default theme is enabled on gadgets, it should apply the default
 stylesheet for the gadgets along with the chart template core styles.

 Also there should be a gadget extension stylesheet available for the
 theme developers. So he/she can overwrite the default gadget styling +
 theme styling (e.g. "gadget.css", just like we have for dashboard and
 portal).

 Let me know the thought.

 Cheers!

[Dev] Equivalent OpenAM policy agent in WSO2 Identity Server?

2016-07-15 Thread Tri Vo Hoang

Dear all,

OpenAM provides a "Java EE Policy Agent", which is a PEP implementation (a
Servlet) to intercept requests and protect an application on the same
container. The nice thing is:

   - admin can control the agent from the central Identity Provider. For
   example, admin can tell the agent to map SAML assertions to a HTTP
   header/cookie/HTTP request params before passing the request to the
   application.

   - admin can choose if the agent allows request according to the decision
   in PDP, or authorization should be enforced through the container's Java EE
   security policies (which may be configured declaratively in the XML
   deployment descriptor of the protected application).

Do WSO2 Identity Provider have similar PEP agent implementation with the 2
features above?

Many thanks

Hi Jerad,

One more thing, considering gadget generation as a one-time thing, how we
are going to support dashboard view theme update functionality. As I
remember we have a functionality to do this right now. So in that case
gadgets need to aware of the current theme and update dynamically.

Re: [Dev] [ES] Too many mysql connections when starting ES instances

My personal recommendation,
Increase the mysql active connections to 350. Please note that this is
bounded to server specs.
Now start 2 servers at a time. Wait 10 mins before starting the other 2
WSO2 servers.
Or else you can always start 1 server at a time every 10 mins. Therefore it
will take 30 mins to start all 4 nodes.

Thanks,
Thushara.
