How do i determine SSO method

Hi,

you can use curl from F5 command line:

curl -i http://www.company.com/

• if the code is 301 or 302, it is a redirect: follow the Location link
• If the code returned is 401, the method can be Basic, NTLM or Kerberos, you must look at the WWW-Authenticate header
  • Basic --> basic
  • NTLM --> NTLM
  • négociante --> Kerberos
• If the authentication page is a form, the method can be forms or forms-client-initiated.

hi stan,

where do i check the information.

i have run the command and got the below output.

Please do not post customer information in this forum.. the method is Forms

to find Forms parameters to configure, I use Firefox firebug, try to authenticate with aaa login and bbb password, and search in the POST data informations.

in you page,

• Start URI is /newEmsg/Pages/Login.aspx
• Form action is /newEmsg/Pages/Login.aspx
• Form parameter for Username is ctl00%24cphBody%24Login1%24txtLoginName
• Form parameter for Password is ctl00%24cphBody%24Login1%24txtPassword

All other POST data must be added to Hidden form parameters with:

One parameter per line, followed by the value (separator is space)

to get them, you must split POST data with separator & and replace = by space.

Some applications add dynamic parameters values to block CSRF attacks. this protection will disallow SSO.

Dear stan,

i an geeting the below logs after enabling debug for sso,

2015-10-06 14:30:58 checking start uri match, start uri: '/newEmsg/Pages/Login.aspx', request: '/newEmsg/Pages/Login.aspx' 2015-10-06 14:30:58 Websso form-based authentication for user 'abc' using config '/Common/E-messaging_Form-SSo' 2015-10-06 14:31:03 metadata len 1130 2015-10-06 14:31:03 checking start uri match, start uri: '/newEmsg/Pages/Login.aspx', request: '/newEmsg/Pages/Login.aspx' 2015-10-06 14:31:03 Websso form-based authentication for user 'abc' using config '/Common/E-messaging_Form-SSo' 2015-10-06 14:31:03 metadata len 329.

And on the browser i am getting an error "This webpage has a redirect loop"

Thanks for your support.

Dear Stan,

I have noticed one thing in the parameter that one of the parameter value keeps on changing. Would be the reason for SSO not working?

_VIEWSTATE (Keeps changing)
