This is an obvious bug. I will try to explain.
I work for 2 companies that have each a set of Enterprise applications we created. A live environment, 2 test environments and a staging environment .
All 4 environments now have around 74 subdomains that we have configured for SSO using basic SAML configuration. All domains use https://<customer>.<domain>.<ext> as identifier and https://<customer>.<domain>.<ext>/saml-login/ as return URL.
When saving a new URL it is always a gamble if they are saved. The Save button goes grey but there will not be a confirmation the URLs have been saved, trying anything on the page will result in a message that there are unsaved items but the Save button is greyed and cannot be used anymore. It has been times it took me 5-10 retries before a save would really save the URLs. As this needs to be done for 2x 4 environments this is a PITA.
But that is not all, on a regular basis (and I expect this to happen when saving a new URL) other URLs (especially return URLs) are dropped. So I have to add them again but this triggers the dropping of URLs again once in a while.
Anybody else seen this behaviour? All help is appreciated
