(ITS#6551) wrapping lines option
by muzzol＠gmail.com 15 May '10

15 May '10

Full_Name: muzzol Version: 2.4.18 OS: ubuntu karmic URL: http://www.openldap.org/its/index.cgi/Contrib?id=4269;page=1 Submission from: (NULL) (62.43.106.218) this is a feature request for making wrapping optional. there's an old discussion here: http://www.openldap.org/its/index.cgi/Contrib?id=4269;page=1 but seems that no one take any final decission. disabling wrapping helps a lot when creating simple scripts and several ldap search utilities have this option (mozldap tools, etc).

This is not a realistic use case. smbk5pwd was written starting in 2004; pam_ldap started supporting LDAP password policy long before then. Anyone running LDAP clients (pam_ldap, nss_ldap) older than that has far worse problems to worry about. >> Ultimately both Kerberos and Samba will just be using LDAP ppolicy. > > Yes. But there is indeed a real need for a solution in the meantime... Yes, in the meantime both Heimdal and Samba use the smbPwdLastSet attribute which is already taken care of.

However, the shadowLastChange attribute is > part of the shadowAccount objectClass - with neither of these names > referring to POSIX. I didn't consider to change the name of the attribute. With POSIX account data I rather wanted to point to RFC 2307 where posixAccount and shadowAccount object classes and the accompanying attributes are defined. Don't get me wrong. I support the idea of setting shadowLastChange even if Howard considers it to be deprecated. And I have no objections to a one-sets-all-of-these overlay. But I'd even like to see this overlay available as standard feature. Since in the current state it has build dependencies to Kerberos libs this is not easy. Only building the Samba support is possible and needs some tweaking of the Makefile. > There are many issues posted online with all the password attributes > except shadowLastChange getting updated. This patch should provide a > solution for many of these cases. Yupp. I already thought these problems long ago when implementing the different password change use-cases in web2ldap. Ciao, Michael.

However, the shadowLastChange attribute is part o= f the shadowAccount objectClass - with neither of these names referring to POSIX. I had considered a separate overlay. However, in terms of purpose, shared code, functionality, and performance, it seems to make the most sense to include this addition into the smbk5pwd overlay. Both pam_ldap and the Samba client support use of exop password changes. Additionally, pam_ldap doesn't appear to support hashing to SSHA (only MD5, which is also the default) - so setting to "exop" also allows for a stronge= r hash of the password to be stored. With the unpatched overlay, doing an exop password change updates userPassword (used by POSIX), as well as all the Samba attributes: sambaLMPassword, sambaNTPassword, and sambaPwdLastSet . This allows Samba clients to use the updated password as well as seeing when the password was last set, but POSIX clients do not see an updated shadowLastChange. This patch adds support for the otherwise missing shadowLastChange, keeping everything consistent. There are many issues posted online with all the password attributes except shadowLastChange getting updated. This patch should provide a solution for many of these cases. > Ciao, Michael. > -- Mark A.

But still it's the question whether we want to have this functionality for various password-related attribute all in on overlay or whether there should be distinct overlays for each account type (posixAccount/shadowAccount, sambaSAMAccount, Kerberos user).

(ITS#6550) Patch for smbk5pwd slapd overlay to include shadowLastChange
by online＠mark.ziesemer.com 13 May '10

13 May '10

Full_Name: Mark A. Ziesemer Version: 2.4.21 / HEAD OS: Ubuntu Linux URL: ftp://ftp.openldap.org/incoming/smbk5pwd-shadow-b.patch Submission from: (NULL) (2001:470:1f11:3ae:dc54:73ba:be16:148) Using the PasswordModify Extended Operation (exop) along with the smbk5pwd slapd overlay provides several benefits, but does not currently include the shadowLastChange attribute of the shadowAccount class. This means the shadowLastChange is missed from update, unless specially done along with a PasswordModify. This patch adds support for updating shadowLastChange into the smbk5pwd overlay for slapd. An added benefit is that once the updated overlay is in effect, write access to the shadowLastChange attribute can optionally be restricted by configuration, preventing users from updating shadowLastChange without actually updating their password. The SHA-1 hash of the provided patch (smbk5pwd-shadow-b.patch) is c29ff518ea4fe03a4c5ee87d07a3af0082256950 . (Please discard "smbk5pwd-shadow.patch".) Patch was generated against HEAD just now, but also applies cleanly to 2.4.21. I am currently using the patched overlay in my current environment without noticeable issue. However, C is not current primary language, so please give appropriate attention to review. This patch file is derived from OpenLDAP Software. All of the modifications to OpenLDAP Software represented in the following patch were developed by Mark A. Ziesemer <online(a)mark.ziesemer.com>.
