Univention Bugzilla – Bug 45424
IE11 redirects to ucs-sso even if ucs-sso is not resolvable via DNS
Last modified: 2018-01-29 17:14:02 CET
Due to certificate issues, a customer "disabled" SSO by removing the DNS entry for "ucs-sso". If the UMC entry on the UCS portal is select, most browsers jump directly to login prompt of UMC. But IE11 still tries to redirect to "ucs-sso.$DOMAIN" which results in an error message.
As discussed, please have a look if it is reproducible and what's the real problem.
I could not reproduce this issue; I tested with the latest IE11 versions on Browserstack (win 7,8.1,10) and a VM with win7 (IE11 v. 11.0.9600). On which windows version was IE11 used?
I think this is fixed in UCS 4.2-3. I saw some javascript tracebacks that localStorage is not defined. That code has been removed. Probably UMC works properly again with IE11. Please REOPEN this bug if the issue occurs again.
