Issue/Introduction

Kerberos authentication is not working for Webdriver monitoring on new OPMS

running "./asm-installer update kerberos -f /etc/krb5.conf"

result in :

ERRO[0000] runtime error: invalid memory address or nil pointer dereference

Environment

DX ASM OPMS 24.* and 25.*

Cause

The issue is related to defect # DE637610

Resolution

1. Upgrade to latest installer version 25.2.26

2. (as root): ./asm-installer uninstall -e docker -t <your token>

3. It does not matter if the uninstall throws errors. Verify there is no /usr/local/asm-installer/cache.json file and if there is, rename it - so it's saved but not present.

4. (as root) ./asm-installer install -e docker -p -a -t <your token>
