ALTER ROLE query is always ran

[lieutdan13]

I'm not sure if this is a puppetlabs-puppetdb or a puppetlabs-postgresql bug, but...

Every time I run the puppetdb class with or without a specified password, the "ALTER ROLE" query is always run. This could be because the puppetdb user doesn't have proper access to the tables to check for user existence?

Its possibly postgresql but hard to say - can you show the full output of your run please?

[jtopjian]

I'm running into this as well:

Notice: /Stage[main]/Puppetdb::Database::Postgresql_db/Postgresql::Db[puppetdb]/Postgresql::Database_user[puppetdb]/Postgresql::Role[puppetdb]/Postgresql_psql[ALTER ROLE "puppetdb" ENCRYPTED PASSWORD 'puppetdb']/command: command changed '' to 'ALTER ROLE "puppetdb" ENCRYPTED PASSWORD 'puppetdb''
Notice: Finished catalog run in 4.17 seconds

I don't think it's a permissions issue. I think it has to do with the query being used to verify the user's existence in the pg_shadow table.

See line 82 of postgresql/manifests/role.pp:

The unless is trying to verify user puppetdb exists with a passwd of $password_hash. $password_hash is simply the unhashed password passed down by the puppetdb module -- no hashing is ever done.

If the unless query is modified to:

unless => "SELECT usename FROM pg_shadow WHERE usename='${username}' and passwd = 'md5' || md5('${password_hash}' || '${username}')"

Then everything works.

So I think this is a bug with the postgresql module?

@kbarber My output is exactly/similar to jtopjian's.

@jtopjian That is what I had found as well. Have you tested the change to the unless parameter? Perhaps you or I could open a bug with the possible fix.

[kbarber]

@jtopjian @lieutdan13 yeah, sounds like postgresql. You guys want to re-open this in that project? BTW - I get the feeling something was merged in recently to solve this ... have a try at the latest postgresql, or 'master' from github.

[jtopjian]

@lieutdan13 Yes, I tested the change and it looks good. I'll be in meetings for the next 4 hours, so if you're able to open a bug before that, please do. :)

@kbarber I'm testing against the latest postgresql module.

[lieutdan13]

@kbarber I am also using the latest postgresql module. I updated this morning.

@jtopjian I will open a bug in that project

Update: postgresql Issue: puppetlabs/puppetlabs-postgresql#216

[kbarber]

Actually, I should keep this open until the source issue is solved. If only for tracking purposes.

[kbarber]

This is fixed with release 2.4.1 of puppetlabs/postgresql.
