[NBLUG/talk] SSH not letting me login

[micxz at micxz.net]

Thanks Dave' 
 
The permissions are the same as the users I can login with. This is only 
happening with my user. 
 
I don't have a secure and don't see anything odd in messages or warn. Checked 
syslog.conf and no mention of secure in there. Perms are "rwxr-xr-x" for most 
all users home dir. 
 
drwxr-xr-x   12 finn     users         832 Nov  3 12:34 finn 
drwxr-xr-x    7 greg     users         536 Oct  7 13:00 greg 
drwxr-xr-x    7 jason    users         608 Nov  2 21:49 jason 
drwxr-xr-x   56 micxz    users        3216 Nov  3 12:30 micxz 
drwxr-xr-x    7 shawna   users         568 Sep 28 16:14 shawna 
drwxr-xr-x    9 yam      users         888 Jul 11 15:17 yam 
 
I just don't know waht to do next. Remove my user and add him again?, I'm 
thinking. But I don't want to have to recreate my whole home dir ~. 
 
OK, I just rebooted. Turns out I cannot login locally anymore with my user at 
all. I cant get a desktop or a shell. This means the user is not working at all 
anymore! what-so-ever. Argh! 
 
Nothing in the logs except: 
Nov  3 13:03:24 neptune sshd[4080]: Failed keyboard-interactive/pam for micxz 
from ::1 port 1070 ssh2 
Nov  3 13:03:27 neptune sshd[4080]: Failed password for micxz from ::1 port 
1070 ssh2
