| Description | This article describes an issue where early FortiOS versions 7.4 and 7.6 would not recognize any local admin that utilized the period ('.') character. |
| Scope | FortiOS 7.4.0-7.4.4 and 7.6.0-7.6.1. |
| Solution |
For FortiGates running earlier versions of FortiOS in 7.4 and 7.6 branches, it is not possible to create users with the '.' character despite it being allowed in previous FortiOS versions. 
When attempting to create the username, the following error is triggered:
node_check_object fail! for name test.user.
This is caused by a logic change in evaluating valid characters for usernames in earlier versions which removed the '.' character. As of firmware 7.4.5+ and 7.6.1+ this has been reverted and '.' is a valid character again with the single stipulation that it cannot be used as the first character in a admin name.
Full list of valid characters are: a-z, A-Z, 0-9, _, -, . |
