[pkg-go] Bug#954240: influxdb: Package installation fails if User "influxdb" is not stored locally (e.g. from LDAP)

Package: influxdb
Version: 1.6.4-1+b22
Severity: normal
Tags: patch

Good day .*.

The installation of the influxdb package fails if the service user
"influxdb" is not present in /etc/passwd but is defined externally,
e.g. in a central LDAP directory (OpenLDAP, 389-dc, ...) or even NIS/NIS+, ...

The postinstallation script looks for the user in /etc/passwd:

[...]
    # create an influxdb group and user
    if ! grep -q influxdb /etc/passwd; then
[...]

and tries to add the account if it not present in this file.

If the account is stored in externally (LDAP,NIS, ...) the
postinst script tries to add the user and will fail, because
the system is able to resolve the account name and UID.

In an "containerized" (e.g. LXC) environment with a central storage
for the InfluxDB data the useraccounts are usually managed in a
central location.

Solution:

In the file influxdb.postinst the lookup in /etc/passwd should be
replaced by "getent passwd ...":
