Bug #7062
openUnable to login to admin interface intermittently, NullPointerException when fail
0%
Description
This has been happening for months. When I log into the Metacat admin panel /{context}/admin, I enter my LDAP credentials and click "Login". Sometimes this takes ~10 seconds (why?) but sometimes it takes minutes and then returns with an error:
LoginAdmin.authenticateUser - Could not log in as: uid=mecum,ou=Account,dc=ecoinformatics,dc=org : Connection to the authentication service failed in AuthSession.authenticate: AuthLdap.authenticate - NullPointerException while authenticating in AuthLdap.authenticate: java.lang.NullPointerException . Please try again
I'll try again and it will go through without error.
