#1440 SSSD fails to store users if any of the requested attribute is empty.
Closed: Fixed None Opened 8 years ago by jhrozek.

https://bugzilla.redhat.com/show_bug.cgi?id=842842 (Red Hat Enterprise Linux 6)

Description of problem: SSSD fails to store if directory server returns an
attribute with empty value. For example:

..
Adding shadowFlag [] to attributes of [ldap_user].
.....
[sdap_save_user] (0x0400): Storing info for user luser1
[sysdb_set_entry_attr] (0x0400): Error: 14 (Bad address)
[sysdb_store_user] (0x0400): Error: 14 (Bad address)

Version-Release number of selected component (if applicable):
sssd-1.8.0-32.el6.x86_64

How reproducible: Always

Steps to Reproduce:
1. Add an empty attribute to one of the user entry.

eg:

dn: uid=luser1,ou=People,dc=gsslab,dc=pnq,dc=redhat,dc=com
givenName: ldap
sn: user1
loginShell: /bin/bash
uidNumber: 1556
gidNumber: 1500
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetorgperson
objectClass: posixAccount
objectClass: shadowaccount
shadowFlag:
uid: luser1
gecos: Ldap User1
cn: ldap user1
homeDirectory: /home/luser1

2. Try to get the information of the above user though SSSD (ie; # id luser1, )

Actual results: User/group membership details missing.

1.
---------
# id luser1
uid=1556(luser1) gid=1500(redhat) groups=1500(redhat)
# getent group g1
g1:*:2000:
# getent group g2
g2:*:2001:
# id luser1

2. (clear cache, restart sssd, try group first)
----------
# getent group g1
g1:*:2000:luser1
# getent group g2
g2:*:2001:luser1
# id luser1
id: luser1: No such user

Expected results: SSSD returns user/group details correctly.

eg: (Added 'ldap_user_shadow_flag = NoAttr' to sssd.conf and I get the results
as expected.)

# id luser1
uid=1556(luser1) gid=1500(redhat) groups=1500(redhat),2000(g1),2001(g2)
# id g1
id: g1: No such user
# getent group g1
g1:*:2000:luser1
# getent group g2
g2:*:2001:luser1

Additional info: As per discussion with Stephen/Jakub on IRC, tested latest
build (which includes
https://fedorahosted.org/pipermail/sssd-devel/2012-July/010602.html ) and the
logs show "LDB error [Invalid attribute syntax]"
