File Server netbios aliases

[DavidePrincipi]

People expects to reach the DC by typing the node name instead.

For instance,

• node FQDN is node1.example.org
• IP address is 192.168.1.1
• DC FQDN is dc2.ad.example.org
• share myshare

Share UNC paths are now:

\\dc2\myshare
\\192.168.1.1\myshare (could not work any more)

We should allow also

\\node1\myshare

Requirements:

• SPNs are added to the computer account entry in LDAP
• Set netbios aliases in smb.conf
• The network DNS resolves the alias correctly (e.g. with a CNAME record)

Tasks:

• Validate NBALIAS for uniqueness in AD
• Change the Server name alias (NBALIAS) in netbios aliases smb.conf parameter
• Add NBALIAS as computer SPN, remove previous NBALIAS from computer SPN
• Add NBALIAS as DNS CNAME in the AD zone
• Implement NBALIAS in DC role
• Implement NBALIAS in MEMBER role
