no entry in /etc/shadow for postgres user?

[_Max_]

Hi,

I am not sure where the postgres user comes from (is this in the initial stage-X tarballs? postgres-8.0.3.ebuild?), but on my system it doesn't seem to have an /etc/shadow entry.

When I su to postgres (to create users on my postgres database), I get the following message:
# su postgres
su: Authentication service cannot retrieve authentication info.
(Ignored)
I assume that is because there is no entry in /etc/shadow corresponding to the postgres user.

Is there a reason that the postgres user doesn't have a password? Should I create a password for my postgres user? Is this a bug?

Thanks.

This is a PAM warning.
Some have used pwconv, which will create a corresponding entry in /etc/shadow for every entry in /etc/passwd.
postgres should not have a password,
One way to get rid of the warning would be to use

Code: Select all

vipw -s

to add just an entry for postgres make sure the second field is '*'.
