Description Stephen Gallagher 2011-02-17 20:50:42 UTC

+++ This bug was initially created as a clone of Bug #677768 +++

Description of problem:
If you looked up some info using unix commands, like id or groups and then changed it using freeipa command - later calls to id will show outdated information:

[root@ipaserver ~]# ipa user-add --first=x --last=y myuser5
--------------------
Added user "myuser5"
--------------------
  User login: myuser5
  First name: x
  Last name: y
  Full name: x y
  Display name: x y
  Initials: xy
  Home directory: /home/myuser5
  GECOS field: myuser5
  Login shell: /bin/sh
  Kerberos principal: myuser5
  UID: 334400018
[root@ipaserver ~]# id myuser5
uid=334400018(myuser5) gid=334400018(myuser5) группы=334400018(myuser5),334400001(ipausers)
[root@ipaserver ~]# ipa user-del myuser5
----------------------
Deleted user "myuser5"
----------------------
[root@ipaserver ~]# id myuser5
uid=334400018(myuser5) gid=334400018(myuser5) группы=334400018(myuser5),334400001(ipausers)

How reproducible:
always

Steps to Reproduce:
1. create user using ipa user-add command, myuser for example
2. type 'id myuser'
3. type ipa user-del 'myuser'
4. type 'id myuser' again - it will show deleted user
  
Actual results:
unix command show some cached info

Expected results:
unix commands always shows up-to-date information about users and groups

I was going to reply that as soon as the deleted user attempts to login, it will be refreshed from ldap, found to be deleted and not reported any more.
Except I have just tested this and it doesn't work.

Reassigning to sssd.

Comment 2 Namita Soman 2011-04-07 02:05:10 UTC

Using
sssd-1.5.5-0.20110405T0615z.el6.x86_64
ipa-server-2.0.0-20.el6.x86_64

went through steps listed above -
user-add...id...user-del..id
And I see the user info.

So are the steps different to verify this bug?
I also logged in as this deleted user, and still could use id to get info about this user.

Comment 3 Namita Soman 2011-04-07 02:07:17 UTC

to clarify - i attempted to log in as this deleted user...login failed. And i could still use id on my server machine, and see info about this user

Comment 4 Namita Soman 2011-04-07 02:25:35 UTC

verified it. 

ran id on client and got the info after deleting, but  after attempting to login as this deleted user, it cleared the cache as expected, and didn't return info when using id anymore. Then when  i use id on server now, no info is returned - as expected.

Comment 5 Namita Soman 2011-04-07 15:16:52 UTC

sgallagh stopped by, and I went through the steps. Verified successfully that the machine I ssh to as deleted user, cleared the cache and didn't list the deleted user anymore.
