Kernel / AD user issue
I have a strange issue for some reason after a certain kernel my user can no longer login. The user is still there but password fails. If I switch back to 3.10.0-693.2.2.el7 .xi6_64 the user works fine. Now the root user works regardless of kernel version. If my server looses power then it boots. With the wrong kernel and the user does not work. I reboot and select the lower version of kernel and it works again.
I thought it was some type of corruption but restoring of data or configs has no effect. Only downgrading the kernel restores the user. I’d like to use the newest kernel but cannot figure out how to resolve this.
