Integrating LDAP users with CageFS

When using LDAP to store user data it requires additional configuration to work properly with CageFS. By default CageFS does not see LDAP user, like this:

# id adam
uid=16859(adam) gid=100(users) groups=100(users)
# cagefsctl --enable adam
Error: user adam does not exist

The problem is that in LDAP pwd.getpwall() function doesn't work by default:

# python -c 'import pwd; print pwd.getpwall()' | grep adam
#
# python -c 'import pwd; print pwd.getpwnam("adam")'
pwd.struct_passwd(pw_name='adam', pw_passwd='*', pw_uid=16859, pw_gid=100, pw_gecos='adam', pw_dir='/home/adam', pw_shell='/bin/bash')

To fix it you should set enumerate=true  in sssd.conf file:

enumerate (bool) Determines if the domain can be enumerated. This parameter can have following one of the values: TRUE = Users and groups are enumerated FALSE = No enumerations for this domain Default: FALSE
