Add Link or Comment to Citrix ADC Logon Page
Update 05-04-2021: Changed the loginschema to show the link above login button and changed script.js to match css.
You are probably reading this as you found out the hard way that rewriting the logon page (AAA virtual server / authentication profiles) is not working/supported. But you do want that extra line in there 😉 Here’s a little tutorial explaining how to do this.
First you need to know that this only works when using custom login schema’s. So when this is needed on a gateway you need to use the authentication profiles features of the Citrix ADC. When you have this is place and working as expected you can continue.
Open the script.js file from your custom theme (located at /var/netscaler/logon/themes/<custom theme name>/script.js)
Add the following part: (Change the link and text to your own convenience)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
// Custom Label Handler for Self Service Links CTXS.ExtensionAPI.addCustomAuthLabelHandler({ getLabelTypeName: function () { return "nsg-custom-label"; }, getLabelTypeMarkup: function (requirements) { return $("<label class=\"label plain\">Click <a style=\"text-decoration: underline;color: #0c559a;\" href=\"https://passwordreset.microsoftonline.com\">here</a> to change password.</label>"); }, // Instruction to parse the label as if it was a standard type parseAsType: function () { return "plain"; } }); //Custom Credential Handler for Self Service Links CTXS.ExtensionAPI.addCustomCredentialHandler({ getCredentialTypeName: function () { return "nsg-custom-cred"; }, getCredentialTypeMarkup: function (requirements) { return $("<div/>"); }, }); |
Here a screenshot how it should look:
Now open your custom logon schema you are using within your authentication profile to edit it. It can by found in /flash/nsconfig/loginschema
Add the following line as last requirement: <Requirement><Credential><Type>nsg-custom-cred</Type><ID>passwd</ID></Credential><Label><Type>nsg-custom-label</Type></Label>
Here is an example of the created loginschema:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
<?xml version="1.0" encoding="UTF-8"?> <AuthenticateResponse xmlns="http://citrix.com/authentication/response/1"> <Status>success</Status> <Result>more-info</Result> <StateContext/> <AuthenticationRequirements> <PostBack>/nf/auth/doAuthentication.do</PostBack> <CancelPostBack>/nf/auth/doLogoff.do</CancelPostBack> <CancelButtonText>Cancel</CancelButtonText> <Requirements> <Requirement><Credential><ID>login</ID><SaveID>ExplicitForms-Username</SaveID><Type>username</Type></Credential><Label><Text>singleauth_user_name</Text><Type>nsg-login-label</Type></Label><Input><AssistiveText></AssistiveText><Text><Secret>false</Secret><ReadOnly>false</ReadOnly><InitialValue/><Constraint>.+</Constraint></Text></Input></Requirement> <Requirement><Credential><ID>passwd</ID><SaveID>ExplicitForms-Password</SaveID><Type>password</Type></Credential><Label><Text>singleauth_password</Text><Type>nsg-login-label</Type></Label><Input><Text><Secret>true</Secret><ReadOnly>false</ReadOnly><InitialValue/><Constraint>.+</Constraint></Text></Input></Requirement> <Requirement><Credential><Type>nsg-custom-cred</Type><ID>passwd</ID></Credential><Label><Type>nsg-custom-label</Type></Label></Requirement></Requirements> <Requirement><Credential><ID>loginBtn</ID><Type>none</Type></Credential><Label><Type>none</Type></Label><Input><Button>singleauth_log_on</Button></Input></Requirement> </AuthenticationRequirements> </AuthenticateResponse> |
Now open your authentication page and you should see the link inserted:

Hi Tobias,
Use the CLI/WINSCP.
Best regards, Jeroen.

Hi Jeroen,
We are curently on NetScaler NS12.1: Build 62.27.nc and I tried to add the password reset link just as you stated but nothing shows up.
The script.js was empty and I pasted your code there ans changed the URL.
The I added the line in the login schema as second-last requirement. I noticed that it missed a “” at the end but it is in your coding.
Also I noticed that the “” in your code is before the loginBtn requirement. In the original code it was at the end. I played around with that but to no avail.
Could it be a problem with CSS?

Which portal theme are you using? Try the rfwebui.
Alex Eckersley · August 25, 2021 at 11:50
We use a custom rfwebui
Jeroen Tielen · August 31, 2021 at 09:32
Hi Alex, the best you can do is create a new theme (based in rfwebui) and start from scratch.

We’ll do that, thanks anyway.
