[omd-users] Nagvis authentication problem

Found a way to authenticate the first time. This may be helpful for others using LDAP authentication with Nagios:

 *   Replaced auth.db with the skeleton one (this gets rid of users that were created with 'Guests' role).
 *   Edited /etc/php.ini and set the timezone (gets rid of a php timezone error; documented in Nagvis FAQ)
 *   Set the following in nagvis.ini.php:
 *   logonmodule="LogonDialog"
 *   logonenvvar="REMOTE_USER"
 *   logonenvcreateuser="1"
 *   logonenvcreaterole="Administrators"
 *   Touched two files:
 *   touch nagvis.ini.php (gets rid of auth.db error - weird stuff here)
 *   touch nagvis-omd.ini.php (also gets rid of auth.db error)
 *   omd restart

Then, logon to Nagvis WUI and manage the accounts as desired.

To set the configuration for future usage:

 *   logonmodule="LogonEnv"
 *   logonenvcreaterole="Guests"
 *   touch nagvis.ini.php
 *   touch nagvis-omd.ini.php
 *   omd restart

So, I'm back to the beginning. Which is good, I guess. At this point I haven't changed any OMD 0.44 Nagvis configuration. So, how do I login and logout of the Nagvis WUI?

I can access the WUI via:
But, this doesn't allow any options.
The Open menu shows the 4 demos.
The Actions menu has one selection - Search (which I'm denied using).
The User menu shows me (jbarnes) as logged in.

Nowhere can I log out. Nowhere can I log in as the administrator. What am I missing?
Thank you, James

Hi James,

a " touch /omd/sites/<site>/etc/nagvis/nagvis.ini.php" should fix your problem, I hat they same issue some time ago with 0.44.

I'm having trouble with Nagvis on OMD 0.44. I broke it. I couldn't find a way to authenticate (my Nagios uses ldap so my username isn't nagiosadmin) so I enabled the audit_log in /omd/sites/<site>/etc/nagvis/nagvis.ini.php by removing the semi-colon and restarted OMD. After that, Nagvis quit working.

The error message when using it is:
SQLSTATE[HY000] [14] unable to open database file
ERROR  Unable to open auth database (/opt/omd/versions/0.44/share/nagvis/etc/auth.db)

I looked for /opt/omd/versions/0.44/share/nagvis/etc/auth.db and, true, it doesn't exist. Neither does the etc directory exist.

I see auth.db in /omd/sites/control/etc/nagvis.

I googled the error and see this but I can't read German:

Has anyone seen this issue and have a fix?
Thank you, James
