I have a huge problem with my Ubuntu since I tried to change the password. My Desktop is connected with a windows domain using pbis-open. From time to time I have to change my domain password and normally use the same password for my Ubuntu then.
This time, after changing domain password (while connected with domain from Ubuntu) I ran into the error "Authentication token manipulation error".
All I tried just made things worse.
The only thing I can still do is login. In gnome, lock screen returns this error and sudo is not working anymore. Sudo is not returning any error here, just don't accept the password.
In simple console I am at least able to use sudo but passwd also returns the autenthication token error before even entering the password.
what I can see in auth log:
passwd: [lsass-pam] [module:pam_lsass]LsaPamCheckCurrentPassword failed [login:foo][error code: 40008]
(Found nothing regarding error 40008.)
pwconv had no effect. pwck grpck show no errors. /etc/shadow don't show encrypted password:
foo::17550:0:99999:7::: sudo passwd -d foo
passwd: password expiry information changed.
pam-auth-update didn't help anything in different combinations.
I am running out of ideas here and any help to fix this is highly appreciated.
