User Operations

User operations available in ctadmn are as follows:

Add New User by:
- Entering a new User ID.
- (optional) Enter a long name (i.e., a text string) for use as a User Description (e.g., for screen displays, where the User ID may be too terse).
- (optional) Enter a User Memory Limit, which is a maximum memory allocation for this particular user that will override maximum memory allocations set at the Server-level (for any user) or at the group level (for any particular group).
- (optional) Enter the User Memory Rule: Absolute, Guideline, or Default. See USR_MEM_RUL in "Configuring the c-treeACE Server" for details.
```
USR_MEM_RULE <GUIDELINE | ABSOLUTE>
```
  The system default rule for c-treeACE Server action when a user exceeds his/her memory limit. This rule is employed only if the System Administrator has not assigned a rule specifically to the user or the user’s primary group.
  
  Valid values are:
  - ABSOLUTE - The memory limit set for a user is to be applied as given, so no additional memory beyond the established limits will be allocated if it is requested.
  - GUIDELINE - The memory limit set for a user guides memory allocation as follows: allow the user to have requested memory beyond the limit set, if it is available, and when another user needs that memory, then it reduces the amount of memory used back down toward the guideline as soon as possible (e.g., by moving memory resident information to disk).
  Default: GUIDELINE

USR_MEMORY
```
- (optional) Enter a user password.
- (optional) Assign user membership in from 1 to 128 Groups (i.e., Group IDs).
- (optional) Enter the first valid date for this User ID.
- (optional) Enter the last valid date for this User ID.
- (optional) Enter limit on consecutive logon failures if different from system default. See LOGON_FAIL_LIMIT in "Miscellaneous Control" for details.
```
LOGON_FAIL_LIMIT <attempts>
```
  The optional limit on the number of consecutive failed logons that causes subsequent logon attempts to fail for LOGON_FAIL_TIME minutes. A logon which fails during this period returns LRSM_ERR (584).
  
  Default: 0 (no limit)
