Not able to login to Now Agent AppIssue From Agent App few users are not able to login to the instance where SSO is configured and auto-redirection has enabled. Users are getting Blank screen after login screen. But in the events logs we can see the events "external.authentication,succeeded" . This means there is no issues with the IDP configuration and user accounts.CauseIn the logs we can see as below: ========= 2020-03-09 01:52:37 (013) Default-thread-2 xxxxx txid=xxxx #172769 /oauth_auth.do Parameters ----------2020-03-09 01:52:37 (015) Default-thread-2 xxxx txid=xxxx *** Start #172769 /oauth_auth.do, user: abc@abc.com2020-03-09 01:52:37 (023) Default-thread-2 xxxx txid=xxxx DEBUG: [code]<code>Security restricted: access for table: oauth_credential, user: abc@abc.com, operation: create -- from class: ReadOnlyRoleAccessHandler</code>[/code]2020-03-09 01:52:37 (023) Default-thread-2 xxxx txid=0dd7e7f3db53 *** End #172769 /oauth_auth.do, user: abc@abc.com, total time: 0:00:00.031, processing time: 0:00:00.031, SQL time: 0:00:00.007 (count: 17), ACL time: 0:00:00.001, source: 185.46.212.151 null =======ResolutionHere the user abc@abc.com is having the role "snc_read_only".
