Issue/Introduction

Palo Alto Global Protect for VPN is used as the firewall for VPN users. The requirement is to have VIP do the 2FA for the VPN users. When logging in as a user with username>password+secure_token would fail. Logins with just username>secure token would work. Logins with username>ldap_password would work.

Restarting the Symantec LDAP Directory Service fails with error 1067 and 1053 on the domain controller.

 

 

Environment

Cause

The backend server logs on the cloud show that the user is able to login with username & OTP, basically, 1 factor authentication. Logging in with the username & password+OTP fails with the above message.

We asked that VIP EGW 9.7 be installed after the server is rebooted.

Resolution

1. Reboot domain controller
2. Remove VIP EGW 9.6.1 from Add or Remove Programs.
3. Install VIP EGW 9.7 and complete the configuration for the userstore and validation server.
4. Run LDAP Sync
