Description Stephen Gallagher 2011-08-25 15:24:21 UTC

Description of problem:
Hello,

We have a big problem with sssd from version 1.5.x (RHEL 6.1 & Fedora 15) and not with version 1.2.1 (RHEL 6.0). We can no longer use sssd (1.5.x) with our LDAP directory, it does not work.

This is due to an addition, see the mail from Stephen Gallagher:

http://www.mail-archive.com/sssd-devel@lists.fedorahosted.org/msg05524.html (Patch 0003)

When searching the primary name of a username, it works well for a DN based on the style:

dn: uid=barras, ou=users, o=epfl, c=ch

but the DN for our organization is:

dn: cn=Benjamin Barras,ou=dit-sb,ou=p-dit,ou=p,o=epfl,c=ch

and as the attribute "uid" is multi-valued:

uid: barras uid: barras@dit-sb (this one just for administrative raison)

this version of sssd wants to find a primary name. As our RDN uses the attribute "cn", it does not match (see log) but in fact, we doesn't want to use a primary name, but only the uid that we give (in this case uid=barras).

We have approximately 12000 entries in our ldap directory and it works from many years ago.

Actually, we modify ours configurations systems for do not use SSSD but nss-pam-pam_ldap and ldapd which work well from many years.

Best regards, Benjamin Barras 




The decision upstream is that we will select the first value returned from LDAP in this case, though it may not be predictable since LDAP is not ordered.
