[lockscreen]: unlock failed #142

Closed star-buck closed 8 years ago

davidedmundson commented 8 years ago

failed where?

star-buck commented 8 years ago

simply unlocking doesnt accept the password... i had to hard reboot... kci20150807 could be also sudo or uid user wrong...

llelectronics commented 8 years ago

Hmm maybe it showing the password prompt but isn't actually locked. So pressing unlock without a password works. I saw that once on one of my machines with an older Plasma 5.3 build though

star-buck commented 8 years ago

no, unlocking without password doesnt work either. Further, even DISABLING the lockscreen in kcm doesnt help, the lockscreen still comes up even though it is UNTICKED.

What if you do sudo loginctl unlock-sessions from the tty when this happens?

Edit: s/session/sessions/g

davidedmundson commented 8 years ago

Urgh, I was just able to lock the live session which should be impossible.

Notes from my investigation so I remember tomorrow morning.

kcheckpass is continually returning "auth failed" even when invoked standalone or forced to use the same service as sddm which we know is working.

It is using PAM properly, going through common-session

Logs below from auth.log show pam is then saying we don't have a valid user... despite clearly knowing it.

Aug 10 00:36:27 david-VirtualBox unix_chkpwd[1825]: check pass; user unknown Aug 10 00:36:27 david-VirtualBox unix_chkpwd[1825]: password check failed for user (david) Aug 10 00:36:27 david-VirtualBox kcheckpass[1824]: pam_unix(common-auth:auth): authentication failure; logname=david uid=1000 euid=1000 tty=/dev/pts/2 ruser= rhost= user=david Aug 10 00:36:27 david-VirtualBox kcheckpass[1824]: Authentication failure for david (invoked by uid 1000)

Though clearly kcheckpass is sending the right user as that's in the logs.

It seems it only affects the ISO; Kubuntu 15.04 + my builds of Plasma are fine.

FYI, I'm leaving this until the rest of the permissions thing in https://github.com/blue-systems/plasma-5.4/issues/141 is fixed, as I think it's likely they're related.

davidedmundson commented 8 years ago

Seems fixed in new image

star-buck commented 8 years ago

seems fixed, closing.
