Ident authentication failed error when connecting to PostgreSQL via PgAdmin III

问题

I'm trying to connect to my postgres server instance using PgAdmin III from the same machine the instance is on, but I keep getting the "Ident authentication failed" error when trying to connect. Here the steps I formed performed to try to achieve connectivity:

I created a new user in Postgres called 'pguser1': user pguser1

I modified my pg_hba.conf file in order to use md5 authentication: pg_hba.conf with md5 auth

I then tried to connect via pgAdminIII, but I've had no success.

What am I missing?

Thanks in advance.

回答1:

Did you create a md5 password for the user or update the user?

If not this may help

U=pguser1; P=yourpassword; echo -n md5; echo -n $P$U | md5sum | cut -d' ' -f1 

Which produces an md5 password. md575a63f65a68540d053ec41f410d9ab24

So the next step would be to update/create the user password .

CREATE USER theuser PASSWORD 'md575a63f65a68540d053ec41f410d9ab24'; 

OR

ALTER USER postgres password 'md575a63f65a68540d053ec41f410d9ab24'; 

You could then login with (in this case)

user pguser1 Password: yourpassword

All the best
