Ah.  That probably reveals the cause of the trouble: you had a corrupt database 
file, which presumably lead to NSS returning the user from `getpwent` or 
equivalent, but the tool that puppet invokes failing to delete the entry.  That 
would lead to exactly this pattern of failure.

Out of curiosity, were you running a long-running puppet daemon there, or was 
this exiting and starting a new puppet process every run where that problem 
happened?

Bug #11111: Puppet incorrectly thinks user exists when it does not
https://projects.puppetlabs.com/issues/11111

Author: Steve Shipway
Status: Unreviewed
Priority: Normal
Assignee: 
Category: agent
Target version: 
Affected Puppet version: 2.7.6
Keywords: 
Branch: 


I have a normal resource definition to ensure the user 'steves' does not exist. 
 On one puppet client, even though the user definitely does not exist, puppet 
still tries to remove it giving this error:

change from present to absent failed: Could not delete user steves: Execution 
of '/usr/sbin/userdel steves' returned 6: userdel: user steves does not exist 

user { steves: ensure=>absent; }

Why is the puppet agent still trying to delete the user when it definitely is 
not there?  I have checked /etc/shadow, /etc/passwd and /etc/group and it is 
not mentioned in any of them.

This also affects another user, but not every one!  I have a list of about six 
that are deleted if found on all hosts, but on this host only two of them 
result in this error.

Puppet agent is running on Linux RHEL5 32bit.
