SUSE Manager with AD issue

I am trying to configured SUMA 4 with LDAP as per but i am facing issues with PAM_LDAP.

suma:~ # pam-config --add --ldap
ERROR: module /lib64/security/ is not installed.
pam-config: invalid option – --ldap
Try pam-config --help' or pam-config --usage’ for more information.
I am not able to find any package which can add LDAP into PAM at SLES 15SP1
Any suggestions are welcome. Thanks
