Undefined array key "mail" at /var/www/html/apps/user_ldap/lib/Access.php#555

[cdthomas9]

I have the LDAP integration tweaked to create the Account Name from the users email address defined in AD. Using the standard uid account name was creating problems getting Exchange to sync using Sendent Sync. I went into the Expert screen and put in 'mail' for 'Internal Username Attribute'. This seems to have fixed my problem, all of my users were synced over but now have their email address used for Account Name within NC. Sendent also seems to be able to sync now, so all is well.

Except for an issue popping up every 10 minutes in the logs.

I now see an entry every 10 minutes of:

Error | PHP | Undefined array key "mail" at /var/www/html/apps/user_ldap/lib/Access.php#555

Does it not like that I typed in mail for the Internal Username Attribute?
