Обсуждение: password politic
Dear All, I am trying to configure the access to the postgreSQL server through web. I would like that someone could give a general idea of how the password politic works in PostgreSQL. Let me explain what I have tried so far. I want to do access to PostgreSQL using password encryption. What I have read is that in that case you need to use the passwd file. I tried to use the commands for adding a user to the system (create user or createuser on the system prompt) but I have seen that in that case, postgreSQL dont add a entry for the new user in the passwd file. BUT if I use the command "pg_passwd passwd" and gives the details for the new user, then it does add the entry to the passwd file, but not in the pg_pwd file where stores the names of the users of postgreSQL (I tried to access through the psql command to the database and the user doesnt exist after only have added using pg_passwd). Does this mean that I have to do this two steps?. I am developing an administration application under C++ Builder and I would like to add users from that application using SQL, trigger, fuctions or whatever. How can I do it without doing it manually? I hope I have explained myseft clearly. Thank you in advance and sorry for my English Miguel

thank you for your short reply but it would much more helpful if you give me any idea of how the password politic works.

dear all, I have been reading through all the documentation about user authentification and still dont have a clear idea. Let me know if I am right. By the way, I am using postgreSQL 7.0.3. In the documentation Ive read that in need to execute in the psql shell the command inserto into pg_group whenever I want to add a new group. I used create group instead (why cant I use it??? ) and checked the table pg_group and got the right result and have an entry for the new group in that system table. Aftewards I add a user with the create user command in the psql shell and granted the access permissions with the "grant" command and added the new user to the group with the command "alter group mygroup add user new_user". Everything seems to work fine, apart of the detail that I need to set the password for the postgres user in the system with the command "alter user". Am I doing everything fine? In the pg_hba.conf file Ive got the following entries: local all crypt host all 127.0.0.1 255.255.255.255 crypt Please give some feedback Thank you very much in advance Miguel ----- Original Message ----- From: Peter Eisentraut <peter_e@gmx.net> To: Miguel Gonzalez <iafmgc@unileon.es> Cc: <pgsql-admin@postgresql.org> Sent: Friday, May 18, 2001 10:04 PM Subject: RE: [ADMIN] password politic > Miguel Gonzalez writes: > > > thank you for your short reply but it would much more helpful if you give me > > any idea of how the password politic works. > > http://www.ca.postgresql.org/users-lounge/docs/7.1/postgres/auth-methods.htm l#AEN13248 > > -- > Peter Eisentraut peter_e@gmx.net http://funkturm.homeip.net/~peter >
