Upgrading to vCenter 8.0 U1 fails with "Failed to start the Workload Control Plane Service" in the wizard.Patching a vCenter from an earlier version of 8.0 to 8.0 U1 fails with "Exception occurred in postInstallHook" in the VAMI.The vCenter SSO domain contains uppercase letters. You can see the case of an SSO domain with the following command: /usr/lib/vmware-vmafd/bin/vmafd-cli get-domain-name --server-name localhost Messages in the /var/log/vmware/wcp/wcpsvc.log file shows a failure like the following: 2023-04-17T13:04:54.017Z error wcp [gcauth/gc_auth.go:94] Failed to parse VC JWKS: invalid character '<' looking for beginning of value2023-04-17T13:04:54.017Z error wcp [gcauth/gc_auth.go:59] Unable to get VC public key configuration : invalid character '<' looking for beginning of value2023-04-17T13:04:54.017Z fatal wcp [gcauth/gc_auth.go:47] Unable to get VC public key configuration : invalid character '<' looking for beginning of value
This issue is due to a flaw in a non-normalized string of the SSO domain being used for comparison with a normalized version.
This issue is resolved in vCenter Server 8.0 Update 1b.
To workaround the issue, update the vmwSTSDefaultTenant name in VMDIR to lower-case by following below steps :Notes: Take concurrent powered-off snapshots of every vCenter in the SSO domain before following these steps.Below steps needs to be performed on the Source vCenter Server Appliance before attempting the upgrade. Domain name is used as vsphere.local in the commands mentioned below. Please change the values depending on the environment, if the SSO domain name is "vcsso.local", replace "dc=vsphere,dc=local" with the "dc=vcsso,dc=local" and replace "vsphere.local" with "vcsso.local" (these texts are highlighted in Blue color).Change the password field in each example before executing the command. Confirm Default Tenant has upper-case in VMDIR using ldapsearch command ldapsearch -x -h localhost -p 389 -D "cn=administrator,cn=users,dc=vsphere,dc=local" -W -s base -b cn=Tenants,cn=IdentityManager,cn=Services,dc=vsphere,dc=local vmwSTSDefaultTenant Example:root@vcsa1 [ ~ ]# ldapsearch -x -h localhost -p 389 -D "cn=administrator,cn=users,dc=vsphere,dc=local" -w "Password123" -s base -b cn=Tenants,cn=IdentityManager,cn=Services,dc=vsphere,dc=local vmwSTSDefaultTenant…# Tenants, IdentityManager, Services, vsphere.localdn: cn=Tenants,cn=IdentityManager,cn=Services,dc=vsphere,dc=localvmwSTSDefaultTenant: Vsphere.Local… Verify the wrong OIDC endpoint with the upper case Tenant using the Curl command curl -k https://localhost/openidconnect/.well-known/openid-configuration Example:root@vcsa1 [ ~ ]# curl -k https://localhost/openidconnect/.well-known/openid-configuration{"response_types_supported":["code","id_token","token id_token"],"jwks_uri":"https:\/\/vcsa1.test.com\/openidconnect\/Vsphere.local","end_session_endpoint":"https:\/\/vcsa1.test.com\/openidconnect\/Vsphere.local","subject_types_supported":["public"],"id_token_signing_alg_values_supported":["RS256"],"issuer":"https:\/\/vcsa1.test.com\/openidconnect\/Vsphere.local","authorization_endpoint":"https:\/\/vcsa1.test.com\/openidconnect\/Vsphere.local","token_endpoint":"https:\/\/vcsa1.test.com\/openidconnect\/Vsphere.local"}root@vcsa1 [ ~ ]# Change Default Tenant to lower-case using ldapmodify: ldapmodify -x -h localhost -p 389 -D "cn=administrator,cn=users,dc=vsphere,dc=local" -W <<EOFdn: cn=Tenants,cn=IdentityManager,cn=Services,dc=vsphere,dc=localchangetype: modifyreplace: vmwSTSDefaultTenantvmwSTSDefaultTenant: vsphere.localEOFExample:root@vcsa1 [ ~ ]# ldapmodify -x -h localhost -p 389 -D "cn=administrator,cn=users,dc=vsphere,dc=local" -w "Password123" <<EOFdn: cn=Tenants,cn=IdentityManager,cn=Services,dc=vsphere,dc=localchangetype: modifyreplace: vmwSTSDefaultTenantvmwSTSDefaultTenant: vsphere.localEOF modifying entry "cn=Tenants,cn=IdentityManager,cn=Services,dc=vsphere,dc=local" Restart the STS Service: service-control --restart vmware-stsdorvmon-cli --restart sts Example:root@vcsa1 [ ~ ]# vmon-cli --restart stsCompleted Restart service request.
