We had a file system full issue and since then some users are complaining about their iXp GUI login failure. They get a file mismatch error when logging in. We tried to reset 2 users password but getting error "Read Filter Required" at save action in iXp Admin Tool.
CA Workload Automation iXp 11.3.5 on supported platforms.
The user configuration files in the $IXP_HOME/etc/user directory for the impacted users went size zero (0), probably an aftereffect of the file system full.
Restore the user configuration files ( <user>.conf ) from backup ( <user>.conf.sav ) in the $IXP_HOME/etc/user directory for the affected users and then re-lauch iXp Admin Tool to reset the user password.
