Error Message
Secure peering was established between CM(Linux) and GUI Client(Windows) .
And a user of GUI Client was added , but User/Password is always asked when GUI connects to CM .


----
Authentication
---
Enter your credentials to connect to the Micro Focus Data Protector Cell Manager: CM hostname

User name:
Password:

[OK] [Cancel] [Help]

Cause
Configured "Web Username" is not appropriate for the GUI connection .
This kind of error can be happened by name resolution mismatching .

Ex.)
- Control Panel\All Control Panel Items\System
Computer name: dpguisys
Full computer name: dpguisys

- nslookup dpguisys
Name: dpguisys.dplab.net
Addresses: 192.168.100.101

- omniusers -list
User Group: admin
Name: ADMINISTRATOR
Group: DPGUISYS
Client: dpguisys.dplab.net
Web Username: administrator|dpguisys|dpguisys.dplab.net
Descr:

In this case, "Full computer name" is not FQDN(Fully Qualified Domain Name) .
The "Full computer name" is short name , but FQDN returns from DNS .

CM recognizes the GUI system as "dpguisys.dplab.net", but GUI system introduces itself as "dpguisys" (Full computer name).
That is confusing situation , but short name(Full computer name) is used for the GUI connection.

Workaround / Fix
Web Username "administrator|dpguisys|dpguisys" is needed to login to CM in this case .

Ex.)
/opt/omni/bin/omniusers -add -type W -usergroup admin -name Administrator -group dpguisys -client dpguisys -pass <password>
