Good afternoon We have recently implemented SSO for Banner 8 via CAS. Our LDAP repository is AD. We are running one CAS server and are now in the process of load testing the capability of CAS to match the load volume tested when using only Banner BEIS authentication.
The tests are set up through WebLOAD. The tests are designed by setting a fixed number of virtual users who attempt to log in at the same time. The tests start at 100, then 200, 250, 275, and 300. At 275 simultaneous attempts to login, the WebLOAD tool receives many Internal 500 errors. Some on the team assess the situation as an indication that CAS can not keep up with the load. Others suspect the tool itself, which must now contend with browser redirects while simulating a high volume of users. Which ever the case, I do know that there are no issues in volume connections to AD. All LDAP authentication steps are made. The Socket failure messages take the following form, but not always at the exact same juncture: 2013-09-05 07:40:39,174 DEBUG [org.jasig.cas.web.support.SamlArgumentExtractor] - Extractor generated service for: https://<server>.alaska.edu:443/<<https://beisregx.alaska.edu/ssomanager/c/SSB> target> 2013-09-05 07:40:39,178 ERROR [org.jasig.cas.web.view.Saml10SuccessResponseView] - ClientAbortException: java.net.SocketException: Broken pipe 2013-09-05 07:40:42,235 ERROR [org.jasig.cas.web.view.Saml10SuccessResponseView] - ClientAbortException: java.net.SocketException: Broken pipe Ellucian, when Atlassian, indicated this error was not fatal, however, our team is seeking a definite assurance that a single CAS server can manage such high volumes during peak times when login attempts can exceed 2000 in the first five minutes. Is CAS incapable of accepting more than 250 simultaneous login attempts without failure? If not, how have teams tested the load so that it met load requirements?
