I am not able to login the SharePoint site, even entering
the correct credentials. By checking this some time, I have found that this is
launch pad web part in SharePoint server. IE settings are not allowing third
party cookies to the Login page.
We can fix this issue by adjusting the Internet Explorer
privacy and security settings.
To Change Privacy settings Go to Tools on right top corner
and Select Internet options. Select Privacy Tab, Move the Privacy References
Slider down to set privacy level for internet is LOW. Click on OK.
To Change Security settings, click on Security Tab and Select
Trusted Sites in the zones. Click on Sites Button to open trusted sites window.
In Trusted Sites window, add this website to the zone box, we
have to enter the domain or IP Address of the SharePoint site, click on Add
button.
Click on Custom Level button to open the Security settings –
Trusted Sites Zone.
In Security Settings – Trusted Sites Zone, “Reset Custom
Settings” drop down list, Select Low. Click Ok to exit the Security Settings
window and Click on Ok to save the settings.
