global protect with SAML SSO authentication failed

[ImFazal]

after upgrading to gp client 6.2.6, we are facing authentication failed issue with few users. 

user clicks to connect and then embedded browser shows error " authentication failed". log shows " Authentication failed: empty password'"

GPS logs shows the following. 

:07:27:816 ----Portal Login starts----

there is no such file " PanPUAC_ " in the folder. seems cookie is not generated.

not all users are impacted but there are few.

we are running 10.2.7-h18

Hi @ImFazal ,

Can you try locating and removing all of the files with a ".dat" extension in the Palo Alto Networks\GlobalProtect directory and also clearing the browser cache of the affected users?
