able to access Lifecycle Manager in VC 7.0 U3 with AD users
In 7.0 U3; when you try to access LifeCycle Manager with AD accounts(e.g. by clicking the Lifecycle Manager icon in the vSphere Client main menu), an error is encountered :
“Authentication failed, Lifecycle Manager server could not be contacted.”
When using an SSO-internal account or the default admin account email@example.com, you can successfully access Lifecycle Manager without issues.
I added the AD user to Administrator SSO Group and still got same issue.
As a workaround you have to use account from the SSO-internal vsphere.local domain, for example firstname.lastname@example.org, to access the Lifecycle Manager.
VMware is aware of the issue and working on a fix. Please subscribe to article https://kb.vmware.com/s/article/85962
UPDATE : Issue is fixed in 7.0 U3a ( https://docs.vmware.com/en/VMware-vSphere/7.0/rn/vsphere-vcenter-server-70u3a-release-notes.html)
