Security :: Specified Cast Is Not Valid - Custom Oledb Role Provider?
Feb 5, 2010
I have a custom oledb role provider that pretty much a cust and past of:
except I've used oledb instead of odbc. I'm connecting to an oracle database and the tables have been created with out any issues. now if I go into the Website Administration Tool and try to create a new role I get the error
"Specified cast is not valid."
I can create a role directly in the database (through TOAD) and the role will show up in the .NET WAT, so I know it can make the connection and read the info just fine. I just can't create or delete or modify a role without the above error.
We are trying to implement Custom Role membership provider for our web app. For authorization we want to check for one more field like Facilityid for the logged on user along with role he has. eg. my User1 having Role1 with Facility1 can access some option and same user role for Facility2 have different option. So is there a way we can extend the existing role/profile provider to authorize user with this additional field along with role assigned.
I have created custome Membership Role and Profile provider using INGRES db. Now I can see my IngresMembership and IngresRole provider in the Provider tab(Select a different provider for each feature (advanced) ) of WSAT but when I clik on security tab I get this error:
"There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store.
The following message may help in diagnosing the problem: Object reference not set to an instance of an object."
What am I missing? Do I need to add code for all override methods for Role provider? I have just written code for the Initialize and GetRolesForUser functions.
I have a custom role provider class that is currently being used by a web application. We are now in the process of migrating several windows applications from VB6 to VB.Net. From preliminary research, I understand that I can use the custom role provider in win forms as well and came across Client Application Services. I understand how the Client Application Services is setup, but can't seem to find how the custom role provider code will be shared between the web apps and the windows apps.
I've just started a small ASP.NET web application. In this project, I need to authenticate the users with Active Driectory. I managed to authenticate the users successfully with Active Directory. But with Authorization with Custom Role Provider, I'm so confused.You see, the user name and password are stored in AD. So, my approach is that after the LoggedIn event of the Login Control, I check if UserName is not yet stored in the Users table yet, then I will store the UserName there. Eventually, I have all the UserName of the AD users store in the Users table so I can assign Roles to the users.
Let's say I assigned UserA to RoleOne. After he logs in successfully, I do some query to look for his Roles.
Where do I keep the Role ticket? In the Cookie or in the session? How does the authorization of ASP.NET role provider work? I want to store the authentication ticket like ASP.NET role prover does too.
There are multiple roles. (Role A, Role B etc) There are multiple input/output fields. (Field A, Field B etc) There are multiple permission levels controlling access to each field. (Read, Direct Edit, Edit With Approval, None) Each role has its own permissions to fields. (Role A has Read Permission to Field A; Role B has Direct Edit permission to Field A etc) Every role can be assigned to users and they are assigned by Geographic information. (User A is assigned to Role A for Continent: Europe - Country: Germany; User B is assigned to Role A for Continent: Europe - Country: France; User A is assigned to Role B for Continent: Europe - Country: France etc) Users can have multiple roles User identity is coming from Windows Authentication.
is it possible to represent this type of kind of multi-layered security model using ASP.NET internal membership/role providers? If so, what should my starting point be? Creating only custom role provider with custom methods and fields be enough?
I am trying to create a Forms Authenticated site and have already used the aspnet_regsql tool to create the necessary logic in my SQL Server DB to hold my data. Now, I am looking to create a custom Membership, User and Role provider for my DB model. I was looking at the following video: [URL]
Now, I get the concept on how to go about it but I notice that this guy uses custom DB Procedures as to the ones that are generated by the aspnet_regsql tool. Can anyone direct me on where I can find info on how to go about building the Membership, User and Role provider class using the DB structure that aspnet_regsql generates? So much junk on google that I am having a hard time finding good guidance.
I have watched the how to video on Creating a Custom Membership provider. So far it works great. My login control interacts well with it etc. Now i've created a Custom Role Provider. I've created a class that inherits the RoleProvider base class and i've added code to each Sub. My question is, what is the best way to implement the role provider, considering I get the Roles etc from the database?
I have created my own custom role provider class "SGI_RoleProvider" and configured properly.
Everything is working fine.
Suppose that I have added a public method say "SayHello()", then how can i call that. Because if i am using Roles then the method is not displayed. If i am forcefully using that Roles.SayHello() then compiler gives the error.
how can i call this. Because creating a new instance of SGI_RoleProvider is meaningless.
I'm creating a custom Role provider based on the ASP.NET Role provider. I have 3 tables. One for Users, one for Roles, one for UsersInRoles.The Users table has no password column because the users are authenticated with ActiveDirectory. That's my approach so far. I can't get the cusstom Role Provider to work, anyone has the same situation like me. How do you make a custom Role provider works with AD?

how to implement a custom role provider which has support for parent and child roles?
I have a requirement to have high level Role permissions as per the usual Role provider functionality. However, I also have a requirement to further breakdown permissions into sub roles. I toyed with the idea of having further role instances for sub permissions but I'd prefer to have a native solution which allows for sub roles.
In this scenario, the "Admin" role is actually 2 distinct roles, one for IT and one for Extranet scenarios. Ideally, there is no association between the 2 "Admin" roles because they are unique sub roles.
[Edit]: Following Igor's comment I feel I should clarify. The aspnetdb is already hosting multiple applications and therefore the use of the Application Name is not possible to segregate the sub roles as it is already being used to seperate the roles by application.
I am new to asp.net and I have a system am trying to edit but each time I debug it, I get errors. The one of the errors is shown below: Server Error in '/starBus' Application.

I try to get the user profile settings with this code. But all items in it are empty, in the database they are not empty. So there is going something wrong. First of oll how can i add a provider to the ProfileCommon ? Maybe i'm there then... the usrInfo is filled well...
I created a custom forms authentication and membership provider and it seems to work fine opening up in WAT, creating roles and adding users. Also when I in my mvc app use it to log users in, it works fine. However it seems to fail to determine a user's role (no errors, but just jump over User.IsInRole(...) lines and Roles.GetRolesForUser(); comes up empty. I got a gut feeling I did something wrong with my configuration, so for now I'll post just that:
This is probably a lame question, but I know little of web development. I inherited a web project that I'm trying to get running locally. I get the mentioned error on line 46.
Line 44: </authentication> Line 45: <membership defaultProvider="AD_MyCompanyName" /> Line 46: <roleManager enabled="true" defaultProvider="ADRP_MyCompanyName_Readonly" cacheRolesInCookie="true" cookieName="MyCompanyName.ROLES" createPersistentCookie="true" cookieSlidingExpiration="true" cookieTimeout="240" /> Line 47: <profile enabled="false"/> Line 48: <customErrors mode="Off"/>
This code works on the old developer's box, but not on mine. I've been working through some TFS checkout issues on his box, assuming it was simply files left checked out. I can't figure out where the providers are added. I don't see them being added in the config file above. In fact, if I search for "AD_MyCompanyName" and "ADRP_MyCompanyName_Readonly", I get no hits in the entire solution. I can't figure out what they are. Not sure why it works on that box if I can't even find the providers being added.
