[389-users] Installation of 389 DS

Hi, I am a newbie on 389 DS, I was following the RDS install document from RedHat Documentation. OS: Centos 7.2 x64 latest updates 389 DS : 389-admin-console-1.1.10-1.el7.noarch 389-ds-base-libs-1.3.4.0-26.el7_2.x86_64 389-ds-base-1.3.4.0-26.el7_2.x86_64 389-console-1.1.9-1.el7.noarch 389-ds-console-1.2.12-1.el7.noarch 389-adminutil-1.1.22-1.el7.x86_64 389-admin-1.1.42-1.el7.x86_64 In the consideration before setting up DS, it's mentioned that we need to add this line to */etc/pam.d/system-authsession required /lib/security/$ISA/pam_limits.so* After adding this line and rebooting the server, I am getting this error when I try to login into it: *Unknown module* in */var/log/secure* I have *login: PAM unable to dlopen(/lib/security/$ISA/pam_limits.so): /lib/security/../../lib64/security/pam_limits.so: cannot open shared object file: No such file or directory* I did read the */etc/pam.d/system-auth* file again, and I found that there is a line like this in it *session required pam_limits.so* My question is : do I need the *session required /lib/security/$ISA/pam_limits.so* for 389 to work properly ? and if yes, how to avoid the above error? if no, does *session required pam_limits.so* do the work? Regards.
