Dynamic CRM keeps asking for credentials

You are prompted for your username and password when you open Microsoft CRM or while you are even browsing dynamic CRM.

Before we start troubleshooting, check if this is happening even in In-Private or Incognito mode of the browser also.

There could be multiple reason for this, lets look at few of them in the order listed here

1) Incorrect credential cached in Credential Manager

Your Windows system stores user credentials on your computer. If the cached credentials are incorrect, you will be prompted for password. This issue usually happens after the password for your domain user account is changed. Before your password changed, you saved your credentials. The stored credentials are not overwritten when CRM triggers the authentication prompt even if you enable the Remember my credentials option.

To fix this issue, you need to remove the corrupted credentials, follow these steps:

1. Click Start, click Control Panel, and then click Credential Manager.

2. Locate the set of credentials that has Dynamic CRM in the name.

3. Click the name to expand the set of credentials, and then click Remove from Vault.

2) Adding the Microsoft CRM Web site to the list of local intranet sites in Internet Explorer

1.     Start Internet Explorer.

2.     Click Tools, click Internet Options, and then click the Security tab.

3.     Click Local Intranet, click Sites, and then click Advanced.

4.     Add the Microsoft CRM server name, the Microsoft CRM server fully qualified domain name (FQDN), and any host header or alias names that you created for the Microsoft CRM URL.

5.     Click Close.
