What's wrong with the {{SignerCommonName}} variable? #6989
Description
Describe the bug
Since installing version 12.2, there have been problems with the {{SignerCommonName}} variable. Everything works fine for local Nextcloud users, but for users integrated into Active Directory, instead of displaying the username in the signature using the {{SignerCommonName}} variable, it displays the string: Array.
To reproduce
-I'm a regular Nextcloud user (users integrated with Active Directory).
When signing a document, in the signature description, instead of my name, "Array" appears...
Expected behavior
93 Instead of the string 'Array', my name should appear in the digital signature description
