This issue occurred because of client are using SP’s metadata.xml file to upload on SSO form. Either they can use IDP metadata.xml or perform following steps –
- Open current metadata.xml file
- Find SPSSODescriptor tag in xml and replace it with IDPSSODescriptor and save it(line 26 & 44)
- Upload this xml file as metadata.xml while configuring SSO
- Then perform Login/Logout flow. It should work
If still issue exist, delete sso configuraton from AEUI and again configure details with metadata.xml & try. Otherwise, in vae database for ae_sso_config table add ssologout url in Endpont cloumn & save & then check sso logout.
