Dell EMC Unity: Failed to add user or group because the name was not found in LDAP database (Error Code: 0x600130) (User Correctable)

Adding LDAP User or Group to Dell EMC Unity Unisphere fails with below error:

Failed to add user or group because the name was not found in LDAP database (Error Code: 0x600130)

There can be two main causes for the issue:
1. The username or group name really does not exist in LDAP.
2. The search path specified in Dell EMC Unity is not correct and the user or group is being looked in a wrong OU.

For the two causes discussed above, below are the resolutions:.

1. Before adding any LDAP User or Group to Dell EMC Unity Unisphere for authentication, the user or the group must be created on the LDAP Server.
If the user is already created, check if the username or group name spelling is correct.

2. Set the proper 'User Search Path' and 'Group Search Path' in Dell EMC Unity Unisphere.
The 'User Search Path' and 'Group Search Path' is where Dell EMC Unity will look for the user or group login information that will be used for authentication.
It can be set in Settings > Users and Groups > Directory Services > Advanced.
