Editing of the PAM configuration files is performed from the command line. Standard OS-level commands and custom commands assist in this activity. All OS-level commands have to be performed separately on both nodes of a Lotus Sametime Unified Telephony cluster.
Adequate administrative permissions
For example, to change the number of cycles before a password can be reused (password iterations number) from the default value of 5 to the new value of 4, the system administrator must perform the following steps:
Parent topic: PAM Framework
- Login to node 1 and get super-user rights.
- Edit password-related files in /etc/pam.d.
- Change "pw_iteration_nr=5" to "pw_iteration_nr=4" as follows:
password requisite pam_passwd_mgmt.so ask_oldauthtok
check_oldauthtok pw_iteration_nr=4 passphrase=0
Manual changes are overwritten when a release upgrade takes place. To retain manual changes, the /etc/pam.conf file must be saved before an upgrade and restored after an upgrade
