Introduction

What is libpam-mklocaluser
libpam-mklocaluser is:
When the user logs in for the first time, a local POSIX user account is created in /etc/passwd and primary group created in /etc/group, and a local home directory is created in /home.
This is useful on roaming computers when the password is set up to be cached by for example libpam-ccreds or sssd to allow login without network connectivity using the password provided by a network authentication service like Kerberos or LDAP.
Other than the caching mechanisms of libpam-ccreds or libpam-sssd / libnss-sssd, the libpam-mklocaluser approach makes the LDAP accounts more persistent on the roaming workstation and robust again credentials cache deletions and such.
