Fwd: [GENERAL] Using LDAP for PostgreSQL permissions/authentication
by Stephan Fabel 17 Sep '13

17 Sep '13

Found on the Postgres mailing list... seems like some folks like to do user provisioning with config management tools rather than LDAP. I don't agree with the guy, but he does point out one issue that I find interesting, which is the absense of a "history" of sorts. Are you guys thinking of some sort of "snapshotting" / COW feature? Would something like that even make sense? -Stephan ---------- Forwarded message ---------- From: Stephen Frost Date: Fri, Sep 13, 2013 at 10:29 AM Subject: Re: [GENERAL] Using LDAP for PostgreSQL permissions/authentication Cc: pgsql-general(a)postgresql.org * Bill Moran wrote: > As documented, LDAP solves a few of the problems we have -- since everyone > will be in LDAP, we can use LDAP's password complexity rules and password > expiration to handle those security requirements, and (of course) when > someone changes their password, they don't have to remember to change it > on every server ... these are big wins.

That last particularly because tools like puppet and chef exist and solve this problem in a better way, imv anyway, than LDAP. Back in the day, I was a big proponent of LDAPv3 and all of the nice things it did, but the complexities involved in "what happens when the network goes away" grew tiring and managing accounts through a config management system which also tracks history of changes, both to the master repo and to the individual systems, wins hands down.

Hello All, We have a openldap 2 nodes running on mirrormode set up. We recently added a new attributetype, after that we are seeing this message on slave node. And i can see the Attributype from ApacheDirectory studio on Masternode but not on slave node. syncrepl_message_to_entry: rid=001 mods check (userid: attribute type undefined) Both the nodes have the same schema file and both are running on openldap 2.4 version. Does anybody get into this issue. *Thanks, * *Chandu *

Attributes rewriting
by Vitaliy Aleksandrov 16 Sep '13

16 Sep '13

Hello, List I've been trying to find a working example to understand how slapo-rwm, slapd-meta and slapd-relay work for the last 3 days with no success. I just need to substitute one attribute by another for a single LDAP user. Lets say I have a posixAccount Object with cn = user1 as shown below. dn: uid=user1,ou=People,dc=localnet uid: user1 cn: user1 objectClass: account objectClass: posixAccount objectClass: shadowAccount ..... Also I have two LDAP users (organizationalRole): admin. simpleuser. I want to configure openldap in a way which allows "simpleuser" to make queries using "(description=user1)" instead of ("cn=user1") to find previously mentioned user object. The only thing I was able to configure is the suffixmassage, but can't find a way how to add rwm-map to my configuration. Could somebody point me to the working example.

slapd.conf deprecate as of 2.5?
by Daniel Jung 15 Sep '13

15 Sep '13

Hi, Quick search through the list shows that slapd.conf will not be supported as of 2.5? Is this still the case? When can we expect 2.5 minor release? Thanks for your answer in advance.

All Data Deleted on Slapd Restart
by Justin Brown 13 Sep '13

13 Sep '13

Hello, I'm new to using OpenLDAP, and I'm having some trouble finding my way on 2.4 with cn=config. After a lot of trial and error, I finally got the initial ldif files setup to initialize the directory. I'll post the configurations below. One of the peculiarities of my Fedora system is that it does not read my slapd.conf, which contains the initial admin password (for cn=admin,cn=config). Therefore, I manually launch slapd -f /etc/openldap/slapd.conf... and run my ldifs. That works great, and I setup regular user accounts. So far so good. Now that I'm done with initialization, I want to stop slapd and start it up with my service manager (systemd). I issue a `killall slapd` (no SIGKILL) or ^C if running with "-d 0" to stop the console session. There are no error messages. Upon restart (either systemd or on the same console), the whole directory is wiped out and reverted back to default. Again, no errors in the system logs, and the only messages are slapd starting and any Apache Directory Studio or ldapsearch queries that I perform. I have tripled checked all of the file permissions (and SELinux contexts) in /etc/openldap and /var/lib/ldap and cannot find any errors. Could someone help me figure out why my data is purged on restart? Here are the ldif files and commands that I run. Slapd from console slapd -f /etc/openldap/slapd.conf -u ldap -d 0 1) Load the schemas for i in $(ls /etc/openldap/schema/*.ldif); do ldapadd -x -f $i -D "cn=admin,cn=config" -w secret; done 2) Load the "backend" config ldapadd -f /tmp/backend.ldif -D "cn=admin,cn=config" -x -w secret dn: cn=module,cn=config objectClass: olcModuleList cn: module olcModulepath: /usr/lib/ldap olcModuleload: back_hdb dn: olcDatabase=hdb,cn=config objectClass: olcDatabaseConfig objectClass: olcHdbConfig olcDatabase: {1}hdb olcSuffix: dc=my-application,dc=app olcDbDirectory: /var/lib/ldap olcRootDN: cn=admin,dc=my-application,dc=app olcRootPW: secret olcDbConfig: set_cachesize 0 2097152 0 olcDbConfig: set_lk_max_objects 1500 olcDbConfig: set_lk_max_locks 1500 olcDbConfig: set_lk_max_lockers 1500 olcDbIndex: objectClass eq olcLastMod: TRUE olcDbCheckpoint: 512 30 olcAccess: to attrs=userPassword by dn="cn=admin,dc=my-application,dc=app" write by anonymous auth by self write by * none olcAccess: to attrs=shadowLastChange by self write by users read olcAccess: to dn.base="" by users read olcAccess: to * by users write by users read I know that those olcAccess rules aren't great, and I plan to fix them once I get past this problem. 3) "Frontend" Config ldapadd -f /tmp/frontend.ldif -D "cn=admin,dc=addressbook,dc=app" -x -w secret dn: dc=my-application,dc=app objectClass: top objectClass: dcObject objectclass: domain dc: addressbook dn: cn=admin,dc=my-application,dc=app objectClass: simpleSecurityObject objectClass: organizationalRole cn: admin description: LDAP administrator userPassword: secret dn: dc=directory,dc=my-application,dc=app objectClass: top objectClass: domain dc: directory Thanks, Justin
