History of "netgroups"
The netgroup feature was implemented for Skolelinux/ DebianEdu as a webmin module ("netgroups"). This module was able to add a host (workstation or server) to a so called "netgroup". If the host was added the host was able to mount the nfs share from the server. It was also use to divide hosts into groups.
Pros:
- webmin module exists and works
Cons:
- it is not userfriendly at all ("go back to save your changes")
- it is dependend on webmin (and webmin will be removed in edge)
Therefor Kurt Gramlich suggest to implement this feature into CipUX. Bededikt Wildenhain is the chief engineer to fullfill this task.
Description of implementation of webmin module "netgroups" (by Benedikt Wildenhain)
Example output of slapcat before adding any host beside tjener:
dn: cn=server-hosts,ou=Netgroup,dc=skole,dc=skolelinux,dc=no objectClass: top objectClass: nisNetgroup cn: server-hosts nisNetgroupTriple: (tjener,-,-) structuralObjectClass: nisNetgroup entryUUID: 33eb0212-b9c5-102a-9cf4-cfcf4b968dd8 creatorsName: cn=admin,ou=People,dc=skole,dc=skolelinux,dc=no modifiersName: cn=admin,ou=People,dc=skole,dc=skolelinux,dc=no createTimestamp: 20060806182912Z modifyTimestamp: 20060806182912Z entryCSN: 20060806182912Z#000004#00#000000
Output after using webmin to add a new server host: dn: cn=server-hosts,ou=Netgroup,dc=skole,dc=skolelinux,dc=no objectClass: top objectClass: nisNetgroup cn: server-hosts structuralObjectClass: nisNetgroup entryUUID: 33eb0212-b9c5-102a-9cf4-cfcf4b968dd8 creatorsName: cn=admin,ou=People,dc=skole,dc=skolelinux,dc=no createTimestamp: 20060806182912Z nisNetgroupTriple: (my-new-server-host,-,-) nisNetgroupTriple: (tjener,-,-) entryCSN: 20061101110153Z#000001#00#000000 modifiersName: cn=admin,ou=People,dc=skole,dc=skolelinux,dc=no modifyTimestamp: 20061101110153Z
So basically an entry named nisNetgroupTriple($hostname,-,-) was added. The following ?CommonNames (cn) have to be electable:
-server-hosts -workstation-hosts -ltsp-server-hosts -printer-hosts -all-hosts?(=member all four groups)
Description of implementation of netgroup feature in CipUX
This feature must be an optional CipUX feature, because there might be installations without NFS or network shares at all. To switch it off and on we use a variable in the "CipUX" configuration section in LDAP.
To switch it on for CipUX >=3.2.12:
cipux_task_change_cipux_config_variable_value CipUX CipUX_Feature_Netgroup 1
To switch it off for CipUX >=3.2.12:
cipux_task_change_cipux_config_variable_value CipUX CipUX_Feature_Netgroup 0
[...] (to be continued)
Description of the implementation of netgroup feature in CAT
The new feature must be available in some GUI. Because ?BenediktWildenhain or ChristianKuelker have Perl knowledge they will implement this first in cat-webmin or cat-web. Due to the fact that webmin will not be in Edge it would only make sense to implement this into cat-web. Others may implement that in the PHP branch of CAT later.
CAT-web uses the LDAP entry in the configuration section:
use CipUX::Cat::Web; my $CipUX_Feature_Netgroup = &rpc($login,$ticket, "cipux_task_tell_me_cipux_config_variable_value", ["CipUX","CipUX_Feature_Netgroup"]) || 0; if($CipUX_Feature_Netgroup){ # do some thing }
[...] (to be continued)
