Hi,

I'm using pam_groupdn for restricting access to some for my servers, by defining user groups as follows.

/etc/ldap.conf (Redhat 5.5) # Group to enforce membership of pam_groupdn cn=group1,ou=Group,dc=example,dc=com # Group member attribute pam_member_attribute memberUid

This works only if the pam_member_attribute is in following format.

memberUid: uid=user1,ou=People,dc=example,dc=com memberUid: uid=user2,ou=People,dc=example,dc=com

Simply memberUid: user1 is not working, is there any way to fix this.

I believe pam_member_attribute will always refer to an attribute containing users DNs. Take a look at the RFC2307bis support.

Second, if a user which dose not belong to this group tries to login server, access is denied by displaying following message.

You must be a memberUid of cn=group1,ou=Group,dc=example,dc=com to login. Connection closed by x.x.x.x

Is it possible to change this message ?

In /etc/pam.d/common-account, for the pam_ldap.so line, use the following:

account required pam_ldap.so ignore_authinfo_unavail ignore_unknown_user no_warn

Thanks, Its working as I expected.

Regards,

Hugo Monteiro.
