- LDAP system authentication is enabled - A LDAP group is defined for a role in the system - Queries to the LDAP server take a long time, for example due to connection timeouts or LDAP referral chasing. This issue can also occur when the system is rebooted if user-manager tries to perform LDAP queries before the management network is accessible.
1. Restart the appropriate user-manager container (system_user_manager on rSeries appliances, controller-userman for VELOS system controllers, and partition<ID>_user_manager for VELOS partitions) 2. Disable LDAP system authentication or remove the LDAP group definitions, and then restart the user-manager container. This will restore connectivity for locally-defined users.
