Re: unable to login particular groups

Hi,

check on the home directories of the two users in /etc/passwd. They must exist.
run pwck

Re: unable to login particular groups

Hi,

We had checked the permissions on all the home directories .

We tried creating a new group and a new user . Then also we get the same error as
No Directory.

MOst peculiar thing is that when we put that user or any user in the group called 'operator' as secondary group he is able to login without any problems.

We have checked everything from permissions , quotas and even HP support is not able to give a proper solution for this.
They had asked us to restore from a old backup.We were told that this is not in their problem database.

Right now we are including the users in operator group till we get a clear idea of the problem and a clear solution.

If any one can give us a solution for this we will be very happy.

Re: unable to login particular groups

Are these NIS users?. Are you running automount daemon?. Do you have BASE or ENHANCED security enabled?

Re: unable to login particular groups

No this is not NIS user& running automount daemon.I think this is base security only.

Re: unable to login particular groups

Are you saying that,

If you put the users into a particular group -> You get 'No directory' error.

If you remove them from the group -> No problem.

Correct?

Can you post the /etc/passwd /etc/group entries for the affected users and group?

Re: unable to login particular groups

Looks like the protection for those directories is just wrong. The home directory should be owned by the user, i.e. muthu (202 instead of 200) and group dba (200 instead of 20).You also probably want to set the mode more restrictive (like 750 instead of 777). You may also want to change the group for the higher level directory , i.e. /users6 (e.g. dba instead of system).

Re: unable to login particular groups

Have you done a "chown -R muthu:dba /users6/muthu"? Note that all the files in muthu's directory need to have the correct protection...

If you add a user using the useradd or adduser command, then all of this should be taken care of.

Re: unable to login particular groups

yes ,i gave -R option.
if I change this user group to gid 20 then user can login.otherthen gid 20 is not working.

Re: unable to login particular groups

This is wierd...

what does "id " say?

Also, if some other user is added to group '200', are they able to login properly?

Re: unable to login particular groups

id users(muthu) gives uid(555) gid (15).
no gid 20 is working group.if anyone add this group then that user can login.

Re: unable to login particular groups

That doesn't correspond to the /etc/passwd entry you gave us for muthu above. The uid and gid of user muthu need to match the directory /users6/muthu and all the files in it exactly.

Re: unable to login particular groups

/etc/passwd entry is
muthu:uOFskAnJ7wurc:555:15::/user6/muthu:/bin/sh

Re: unable to login particular groups

muthu:uOFskAnJ7wurc:555:15::/user6/muthu:/bin/sh

if change gid 15 to 20 then this id is working.

Re: unable to login particular groups

Please only change one thing at a time!

The information you gave about the directory still doesn't match the latest information you gave about the passwd and group file. Please try this and post the results:

chown -R muthu:users ~muthu
ls -al ~muthu
su - muthu

The above should be executed as root using ksh or bash and assumes that the "users" group has not been modified from the default (15).
